Types Of Stem Cells Research Studies
Stem cells can be used as a viable aid for the treatment of a wide variety of ailments that have been otherwise left untreated by several other modalities of medicine. The brilliance of stem cells, however, does come with a price. Determination of the treatment cost involved in stem cell therapy can be done with ease by regarding the diagnosis, organ involved in the treatment, administration process and the follow up procedures. In the rarest of cases, a physician might charge some bucks extra to pay off the licensing fee that he/she had to pay to the further sources for obtaining a fresh stock of stem cells. For instance, a standard procedure of osteoarthritis could fall in the price range of 5000$ to 7000$ inclusive of the charges of all the aforementioned norms. Extraction of bone marrow is supposed to be carried out in a standard manner by a medical professional who is licensed for performing the procedure of liposuction. Geographic location could be yet another deciding factor in determining the final price of a stem cell treatment. A simple yet invasive procedure of the extraction of bone-marrow tissue can be arranged by a payment of 15000$ to 20000$. Although, diseases like Crohn’s, MS (multiple sclerosis), Alzheimer's might require a professional with a higher degree to carry out the stem cell procedure as they would require involvement of the entire body in the stem cell treatment.
More specifically, stem cells can be an indispensable part of a repair mechanism that might be required for either an organ or tissue after its confrontation with some form of injury or disease. While stem cells are present in different locations inside a body, a concentrated source of stem cells can be the bone marrow. It is for this reason that bone marrow is targeted as the most assured source for extraction of stem cells if any need should arise. Stem cell extraction is a painless procedure. The stem cells extracted via bone marrow aspiration are administered directly to the site of the body that requires immediate attention. Some physicians opt for the extraction of stem cells via pelvic bone. Upon derivation, these stem cells are concentrated by ten folds with the process of ultracentrifuge. The extraction procedure for stem cells usually takes up to half an hour. This procedure is carried out under the effect of local anaesthetics such as the xylocaine or lignocaine.
Post-operative complications can be tough but they should be held in mind when intending to attend an appointment for a prospective stem cell therapy procedure. As it may come as a surprise, stem cell therapy does pave a way for complications in cases that enclose some form of a pre-medical condition. One of the most oddest of the complications that could possibly arise at the time of follow-up would be of the graft v/s host disease. In this complication, body of the patient rejects the draft cells. For instance, in the case of any cancerous condition the extraction of stem cell for therapeutic use is ideally done from a host/person other than the patient. This cautious step prevents the accidental infiltration of any cancerous cells into the stem cell culture. So, the stem cells are infiltrated from some other body that’s in a salubrious state. This process of standard stem cell transfer in the case of a cancer patient would be known as the ‘allogeneic’ treatment. While most of the cases turn out to be okay, some cases might exhibit the dimensions of the graft-versus-host disease (GvHD) by invoking the symptoms like thickening of skin, and inflammation of tendons in less than 24 hours of stem cell treatment. Yet another shortcut through which stem cell therapy complications could make their way into the body are blood transfusions. When being used for alleviating the symptoms of cancer, it is advisable to maintain a gap of approx. a week between the introduction of stem cells into the body and the ongoing chemotherapy, radiotherapy sessions.
Stem cell therapy when used in a non-invasive form, stem cells can help in avoiding a tedious, surgical procedure at all costs. Stem cells can be classified into the following on the basis of their source:
1) Embryonic stem cells: As the name might suggest, they are the stem cells extracted from an approx. week-old embryo. The only difference herein is that the embryo is developed in a lab's petri dish instead of human body. The in-vitro fertilization assures the pluperfect growth of pluripotent stem cells. A huge advantage carried by the pluripotent or embryonic stem cells is of their flexibility of use in any organ or part of the body.
2) Non-embryonic stem cells: A common misnomer associated with this class of stem cells is ‘adult stem cells’. Non-embryonic stem cells can be extracted from adults as well as kids. Unlike the petri-dish stem cells mentioned above, these cells are extracted from the sturdy tissues of the body. Since they are not exactly pluripotent in nature, they can be of use only in the specific region of the body from which they have been extracted from their original recipient.
3) iPSCs : iPSCs are the reformed version of non-embryonic stem cells. iPSCs come in handy when the stem cells required for the procedure need to be in exact likeness of pluripotent cells. When infiltrated into the human body, they diversify into different forms of cells and refill the scarcity of standard cells for any organ or tissue in the body. Basically, iPSCs are genetically altered versions of the non-embryonic stem cells. By doing so, the scientists have made it possible to cut down the incidents of stem cell rejection to almost a zero.
4) Amniotic fluid stem cells: These are the stem cells that bear a direct connection to the amniotic sac and are gathered via umbilical cord of the newborn immediately after the delivery of a child. A huge asset that the amniotic fluid stem cell possesses is that of of longevity. They can be kept in a freeze-dried state for years and then used when the appropriate time arrives. Most of the cases that have been attended in the past few years with the use of amniotic fluid stem cells were either pertinent to a cancerous condition or hereditary blood issue.
5)Mesenchymal stem cells are the stem cells that can be found in a fresh state in the bone marrow, fallopian tube and other organs of the body. Transforming growth factor-beta 3 is one of the prime supplementations that can prove to be beneficial in multiplication of mesenchymal stem cells and therefore in the repair of bone. A non-invasive approach that can be adopted in the non-malignant cases is of the multiplication instead of infiltration of the mesenchymal stem cells within the bone marrow or any other organ where they may be required to cure a disease. Epithelial–mesenchymal transition is the transition of epithelial cells to mesenchymal cells by shed of their polarity and adhesiveness. This transition can prove to be a pathbreaker in many ways. For instance, in the case of fibrosis of liver conversion of epithelial cells to mesenchymal cells can assure internal repair of the organ without the use of any external aid such as the drugs, transplants or supplements.
6)The neural stem cells on the other hand are cells that concentrate in the central nervous system. Age presents itself in the form of memory. These cells be valuable in the process of adult neurogenesis. When infiltrated into the region of hippocampus, neural stem cells are capable of handling the memory and mood issues with ease. Neural stem cells own the explicit property of self-renewal in-vivo too. Neural stem cells can be used during any stage of their life cycle. Standard stature of metabolism can bear a direct impact on the health of neural stem cells. This fact can prove to be an essential indication in postoperative maintenance of health after the stem cell treatment has been performed for adult neurogenesis. In-vitro proliferation of pluripotent stem cells is one of the latest advances that helps in ameliorating the signalling process in the central nervous system of elderly people who suffer with schizophrenia and bipolar disorders.
Many universities worldwide support the idea of furthering the use of stem cells. The only clearway available to advance the use of stem cells in every aspect of science would be of refining their differentiation process. The process involved in tweaking of stem cells during the research is referred to as the direct differentiation. For instance, if the stem cell extract from any organ or tissue could be directed towards differentiating specifically into the langerhans cells, the prognosis for an advance case of type 1 or type 2 diabetes could be bettered. Some of the other medical conditions that can be attended to by performing the process of direct differentiation on stem cells of any origin would be:
- 1.Injury of the spine
- 2. Heart condition
- 3. Burn injuries of varying degrees
- 4. Bursitis
- 5. Impairment of hearing
- 6. Parkinson's disease
The frontmost part involved in the extraction of a stem cell concentrate is the conditioning process. In today’s times there are three kinds of conditioning procedures that are favored ahead of conducting a stem cell procedure:
Myeloablative conditioning: Its an initial stage procedure that involves circumferential scorching of cancerous region of the bone marrow of the person who going to receive the stem cell transplant. Myeloablative conditioning process involves a series of chemotherapy or radiation sessions to spifflicate the bone marrow of the recipient. It is a standard procedure performed before the commencement of a hematopoietic stem cell transplant. The blood count levels that get altered during this procedure get replenished within a period of 2 to 6 weeks. Myeloablative conditioning does an excellent job of immunosuppressive therapy before the transplant. This form of conditioning is primarily used for the cases the are either severely immunocompromised due to some disease or are too elderly. Myeloablative conditioning is the procedure of choice for prepping the paediatric cases of allogeneic hematopoietic cell transplantation. In addition to avoiding an incidence of rejection, myeloablative conditioning keeps a watch over the plausible issue of postoperative leukaemia that might come up at the end of the treatment. Busulfan is a alkylating agent that is administered intravenously into the system to handle any of the plausible side effects of the original chemotherapeutic drug, Pentostatin. The usual dosage of busulfan varies between 1 to 4 times in a day based on the patient’s condition. For instance, a patient with age close to 40 would require only a single dose of I.v busulfan (51mg). Fanconi anaemia is a variant of anaemia that presents various forms of physical anomalies and makes the patient more susceptible to malignancy. A prominent characteristic of this disease is the unstable pattern of chromosomes which thereby increases the sensitivity of the patient’s body to chemotherapy and radiation therapy. A case of fanconi anaemia cannot afford graft v/s host disease at the end of stem cell therapy. It is for this reason that myeloablative conditioning is regarded as the conditioning of choice whenever allogeneic hematopoietic stem cell therapy is used as curative therapy in this variant of anaemia.
Reduced Intensity conditioning: Reduced intensity conditioning is a flawless regimen proposed for the stem cell cases that require a very meagre amount of exposure to chemotherapy and radiation. Reduced intensity conditioning is performed by adopting two approaches one of which involves the use of busulfan. This version of RIC is adopted in cases that encompass some form of bone marrow dysfunction, underdevelopment of the blood cells in bone marrow, leukaemia and metabolic disorders. The prime vantage of performing RIC with busulfan is of lowering the intensity of any of the aforementioned diseases and therefore the incidence of any complication after stem cell treatment. The second approach that has been suggested is of the use of fludarabine with RIC. An additional post-operative step involved in this approach is of lymphocyte infusion that is performed towards the end of the therapy to avoid any incidence of relapse of the pre-existing condition. Reduced intensity conditioning induces a temporary suppression with the use of myelocytes.This final step initiates a chain reaction of mixed chimerism that stabilizes the graft. Reduced-intensity conditioning can be helpful in the cases of total body irradiation that would involve ablation and immunosuppression. Since, the immune system of children does not allow the amount of evasion involved in the process of myeloablative conditioning, RIC would serve as a more favourable version of conditioning. Also, Hsct can be regarded as the sole treatment of choice in cases like thalassemia major and several other blood deformities.
Non-Myeloablative conditioning: Non-myeloablative conditioning can prove to be an ideal version of conditioning in the cases of hemoglobinopathy. Hemoglobinopathy is a hereditary condition that presents with an abnormal constitution of of globin complex of the hemoglobin molecule. Hemoglobinopathy presents the signs of pale skin, breathlessness and fatigue. The strategy involved in success of non-myeloablative conditioning is the use of total body irradiation that involves a dose of approx. 300 centigray. Non-myeloablative conditioning eliminates the use of chemotherapy during stem cell procedure. Majorly, all the cases that used non-myeloablative conditioning as a conditioning option involved the participation of donors that were either HLA-identical siblings or related to the patient in some way. Also, the donor stem cells in such cases were extracted from peripheral blood vessels instead of the bone marrow.
A full-fledged recovery from the standard procedure of stem cell therapy can be expected within a period of 6 weeks. The feeling of well-being from then on can be expected to improve in the next 6 months. The foremost caution to be that needs to be conformed to post-operatively is of avoiding heavy exertion. The toughest caution to follow can be of hemming painkillers like aspirin, advil to avoid a negative impact on stem cells. The safest pain-control option for the first few weeks would be paracetamol. The standard regimen to follow after stem cell treatment would be 2 capsules of paracetamol (500mg) per day.
As many eager patrons may know, it was during the onset of the 19th century when Alexander Maximow stated that the origin source of all blood cells are the hematopoietic stem cells. This substantial fact furthered by Alexander Maximow was used in practice for the first time in 1968 by Dr. Good during a bone marrow transplant. Based on the compliant use in general practice, there are essentially two forms of stem cell transplants that are carried out:
Autologous stem cell transplant: During this procedure, the stem cells that are supposed to be used during the therapy are extracted from the patient’s own bone marrow. This approach nullifies the chances of rejection to any of the infiltrated stem cells. Nevertheless, hygiene is a factor that would still play a crucial role in deciding the patient’s overall recovery during the follow-up procedures. Also, autologous stem cell transplant saves all the extra expense and energy that is would have been spent otherwise in finding a suitable donor. The only medical case that overruled the use of autologous stem cell transplant was that of cancer. In any form of cancer, the immune levels of the body are too low to donate stem cells. In fact in such a scenario the stem cells from the patient might carry the risk of being cancerous and can therefore worsen the situation by presenting a relapse.
Allogeneic stem cell transplant involves the following phases:
- 1.Patient is given chemotherapy and radiotherapy to control the conduct of malignant cells.
- 2.The second phase involves infiltration of healthy stem cells and recovery of body’s own blood cell counts.
- 3.The third phase involves recovery of the immune system. This is the stage in which the patient needs to stay clear of any plausible, incidence of infection.
- 4.The last phase is of convalescence. By this phase, the immune system has returned to its normal functioning. However, if the case involved is that of a child, it is recommended to opt for a cautionary round of vaccinations to affirm the desired level of immunity at the end of the therapy.
Some of the most usual systems recommended and made available commercially for development of stem cell culture are organoids and 3D cell culture . The reagents used in these readymade and commercially omnipresent cell culture bases fused for stem cell culture are Putrescine, recombinant human insulin, progesterone and human transferrin. Recombinant human insulin is produced after hours of biosynthesis of microbes such as the E.coli and yeast. Recombinant human insulin is the prime component involved in multiplication of cells. Optimal temperature for storage of recombinant human insulin is -20 degrees. Putrescine is a remnant diamine formed by the putrefaction of amino acids named arginine and ornithine. Putrescine comes into its full effect on the second day of the culture and displays its effectiveness in the form of stimulated cell growth. For instance, the mesenchymal cells extracted from a healthy bone marrow are capable of gaining from the cell proliferation potential of Putrescine when a standard concentration of 100µmol is used in vitro for 2 to 6 days. Human transferrin can prove to be an important tool in the transmission of iron among the stem cells during their proliferation. Progesterone when used in stem cell culture contributes by fastening the differentiation of pluripotent stem cells.
While there are a plethora of cells existent in our body. Stem cells are the ones that own the uniquely-built cell system which allows them to regenerate and replace the damaged cells. It is their capacity to regenerate and divide into different other forms of specialized cells that makes them stand out of the crowd of the cells in the body. Stem cell are either used for research to enhance their use in medical field or in therapy to redefine a lost cause. For instance, when stem cells replicate into dermal cells they can be used for dawning a new skin onto any area of the body that might have received any degree of burn. The standard function for any cell in our body is defined by gene expression. The term gene expression would pertain to the expressed or repressed forms of a particular group of genes. Gene expressions are further regulated by the movement of signals through your body at a certain time. Scientists make use of the gene markers to foster the process of differentiation in stem cells. During the developmental stages of an embryo, a multitude of chemical and physical signals get manifested in the form of secretion of chemicals, cell-to-cell networking and mechanical strain which is explained by the movement of embryo within the amniotic sac. The aforementioned set of signals cause an immediate change in the activity quotient of genes and therefore determine a certain level of cellular differentiation.
A similar process when performed in a lab by a group of scientists would involve the use of a petri dish that features an environment mimicking that of the amniotic sac. In order to induce a process of differentiation, petri dish is exposed to identical signals namely the growth factors. Co-culture environs are created to manage the interactions between cells. Keeping a record of the response received from the neighboring cells is as essential as keeping a track of the original stem cells. Yet another practice encouraged in co-cultures is of using the cells that produce growth factor and therefore boost the differentiation for stem cells. An advanced version of culture media available these days is of the three-dimensional culture. Three-dimensional culture is composed of a group of cells that have been clustered together in the form of spheres. Collectively, these clusters are known as embryoid bodies. They are induced in the culture media with the purpose of creating the effect of mechanical stimulation which under normal circumstances in the body would be created by the movement of embryo within the amniotic sac. In a way, a three-dimensional culture media would be more precisely replicating the exact environ that exists in the developmental stage named gastrulation in the embryonic sac. Gastrulation is the developmental stage during which the the cell lineages take form through the process of differentiation. Last but not the least, would be the involvement of inhibitory growth factors. Inhibitory growth factors make sure that the signals that initiate the process of differentiation of the stem cells to the desired cell types stays restricted.
Wharton’s Jelly is the most exclusive source of stem cells that is made available commercially for any of the standard stem cell procedures these days. Naturally, wharton’s jelly is a gelatinous mix that that can be found only within the umbilical cord. The commercially available Wharton’s Jelly is composed of all the standard elements with an osmolarity quotient that is unquestionable. The standard ingredients of Wharton’s jelly would be the hypertonic solution of NaCl, mannitol, MgCl2, and KCl . All of the aforementioned ingredients of Wharton’s jelly serve as ideal requisites for culturing the stem cells. Wharton’s jelly can be more specifically ideal for culturing the stem cells that have been obtained directly through the amniotic fluid or umbilical cord. The reason behind this fact could be the standard nature of jelly’s gelatinous composition which assures the same level of insulation and protection to the stem cells as provided by Wharton’s jelly within the body.To conclude, all the elements totted into the base material of stem cell culture are capable of contributing to the growth of stem cells in some or the other way irrespective of the source from which the stem cells have been derived.
Oftentimes, platelet rich plasma therapy has been compared with stem cell therapy for gaining an insight into the regeneration potential of body parts and plausible relief for the chronic pain ailments. Platelet rich plasma therapy involves the use of platelets in the incapacitated region of the body. PRP injection could cost a lot lower than stem cell therapy. However, the regeneration potential of stem cells exceeds that of platelets which furthers the use of stem cells in more complex procedures . A common area of use that prp injections and stem cell therapy could share would be the redressal of lost hair. Stem cell transplant can be an apt procedure for the patients who appreciate a minimally invasive procedure for growing back hair. The procedure involves harvestation of a tiny skin samples with the aid of punch biopsy. The instrument used In punch biopsy is as easy as a stapler. The skin sample recovered with the use of punch biopsy is further replicated in a lab and are then streamlined with the use of centrifugal force via a machine. The stem cell suspension obtained from the centrifugal machine is replaced back onto the area of the scalp that displays baldness. The entire procedure of stem cell therapy that is meant for hair re-growth is performed on an outpatient basis under the effect of local anesthesia. The commonest hair loss conditions that can claim a relief with the use of refined stem cells are male androgenetic alopecia, androgenetic alopecia and cicatricial alopecia. Cicatricial alopecia is an incidental version of alopecia that follows any injury that presents sooner or later in the form of scarring. Cicatricial alopecias can prove to be a handful when they are a part of huge syndrome such as lichen planopilaris, discoid lupus erythematosus, and folliculitis decalvans. Acne keloidalis is a scarring condition that can be witnessed in the pubescent age of african people. The alopecia can be considered as a condition that follows the loss of human hair follicle stem cells (HFSCs). Hair follicles, like every other organ are under the constant surveillance of neuroendocrine-immune network. Although, there is a possibility that the connection between the hair follicles and the network might get entangled at some point due to the following reasons:
- Relatively lower amounts of MHC I antigens
- Dysfunctional langerhans cells
- Ingestion of immunosuppressive drugs that might have been otherwise been in use for treating another ailment
Pluripotent stem cells can be used in a wise way to replenish the hair follicles by:
- A. Rooting for the correction of pathologies that contributed to the loss of hair follicles in the first place
- B. Regeneration of an entire hair follicle by replenishing the bulge of cells that form every single hair follicle
- C. By performing a tissue culture of stem cells that furthers the process of neogenesis of hair follicles and by their use as a stable layer of centrifuged stem cells on the bald spots/area.
Degenerative knee cartilage condition is a general complaint that follows your way to the old age. The further trouble in such a condition can be avoided by opting for mesenchymal stem cell infiltration over knee replacement. Knee replacement procedure as many might know would require 6 months of post-operative physiotherapy to release the stiffness of stitches and thickened skin around the operated joint. Non-embryonic stem cells bear an equal chance of reversing the degenerative process of the cartilage by raising the immunity levels around the inflamed region of the knee joint. After an appreciated change in the immune levels, the degenerative changes around the knee joint follow a prolapse. A similar effect can be expected in the cases of sports injuries such as the ailing knees and tennis elbow. Healthcare costs can come around as onerous when the treatment involves musculoskeletal disorders, slipped disc and lower back cartilage degeneration. Stem cell therapy proves to be a breakthrough for spinal injuries and degenerative disorders. MSCs (mesenchymal stem cells) and embryonic stem cells contribute in a big way to the regeneration of the extracellular matrix of every spinal disc involved in the aforementioned health issues. Under the normal circumstances, it would be the pericytes that can be counted on for the proliferation of mesenchymal stem cells to combat any of the spinal issues. In an event of any obstruction in the instinctive procedure carried out by pericytes, the infiltrated MSCs would favourably exert an immune response that would take care of the inflammation in the affected regions of the spine. Needless to say, stem cell therapy assures the patient of not just resolving an old and bothersome spinal condition but also putting an end to any further degeneration in the spinal discs or tissues. Cytokine is the main enzyme involved in degeneration of spinal discs. The anti-catabolic property of stem cells makes the enzyme cytokine dormant enough to put an end to any further degeneration.
Parkinson’s disease is a condition that primarily causes a deficit in the adequate functioning of motor neurons. Stem cells such as the embryonic stem cells and induced pluripotent stem cells (iPSCs) are capable of inducing dopamine into the body and can assure an improvement in the motor symptoms of the central nervous system. The commonest motor symptoms that can be relieved by stem cell therapy are resting tremor in the regions of foot fingers and jaw, bradykinesia, stiffness of muscles and micrographia. Since parkinson’s has a tendency to get carried on from one generation to another, stem cell therapy can also prove to be a preventive measure by emerging as a reliable source of dopamine. The recent version of transplants have been centred on the correction of non-motor symptoms too. Most of the novel trials that involve the correction of non-motor symptoms follow a similar pattern of dopamine production via stem cells as do the studies that were directed towards correction of the motor symptoms.
MSCs that are capable of invariable amount of differentiation extend the benefit of their involvement in heart conditions too. Recently conducted C-CURE trial was a hearty endeavour that was conducted on European subjects for testing the efficacy of stem cells in heart conditions. MSCs gathered after an in vivo boosted preconditioning in culture media delivered a third degeneration of stem cells . These cells were confirmed as the cardiopoietic cells that can be used for recovery from an ischaemic heart disease. During the clinical study, a couple of proteins were came upon that could reassure a steady process of cardiogenesis.The identified proteins were bone morphogenetic protein 4 and activin A. As a part of the trial, these proteins were injected into the culture media with the developing stem cells in it so that the cardiogenic properties of the proteins could be completely acquired by them. As a result, an instant improvement in the condition of the heart was valued in the form of a tremendous improvement in the pumping capacity of the heart.
A recent enterprise organized the combined stem cell pilot experiment with CRISPR, a bacteria-derived gene-editing tool. The prime purpose of this research is treatment of beta-thalassaemia with the use of CTX001 ( a thorough combination of stem cell protein named CD34, and genetically altered stem cell named CRISPR-Cas9). Beta thalassaemia is a blood related disorder that involves disruption in production of haemoglobin in the blood. As a result, the oxygen carrying capacity of blood is compromised and shortness of breath becomes a regular symptom. The similar kind of research would be prospectively begun around the middle of this year which would be targeting a cure for sickle cell anaemia with the use of CTX001. It is a noteworthy fact that the changes introduced into the stem cells with gene alteration do not get forwarded to any of the germline cells such as the sperm and ova and therefore the changes induced would stay confirmed only to the generation involved in the scientific research.
Nanoclay-reinforced hydrogel is a medical product that might come as a anew to many people who are familiar with the uses of stem cells. Nanoclay-reinforced hydrogel is composed of hyaluronic acid, clay and alginate. The porosity quotient of this hydrogel is adequate enough to permit the inflow of nutrients through the gel. When combined with stem cells from any source, this gel was capable of ensuring its efficacy by initiating the process of osteogenesis in an in-vitro piece of bone with defective osteum. A theoretical explanation provided by the researchers to validate the osteogenic potential of nanoclay-reinforced hydrogel is that the mineral structure of the product is ideal for promoting the transformation of stem cells to bone tissue. Further in-vivo trials of this product are on their way in Spain. According to the prelim native studies in this regard, the hydrogel when implanted into the patient’s body would be able to assimilate stem cells in the region of application and start-off a process of rejuvenation for stabler stem cells. Apart from the population affected by bone defects, people especially women over the age of 40 who find it tough to deal with the condition of osteoporosis can benefit a lot from the regular use of nanoclay-reinforced hydrogel. Although, some of the controlling factors that might challenge the efficacy of this product would be conditions like hormonal imbalance, or the ones that require regular use of immunosuppressive drugs.
ORIG3N is a biotechnology unit that assures of being biggest repository of blood cells in the world. The base architecture of these blood cells is used for production of iPSCs. The other two medically productive segments owned by ORIG3N are based of theorems of gene’s methodology. The segment that involves the storage of stem cells at ORIG3N is called LifeCapsule. The stem cells that are derived from various sources are preserved in a frozen state. ORIG3N takes a special interest in promoting the use of regenerative medicine in the future. Regenerative medicine involves use of tissue engineering and human physiology at the molecular level to restore the functions of various organs.
Yet another use to which the stem cells have been put to is of verifying the reliability of any new drug or as one might state, ‘Do the drugs really work in the manner that they proclaim?’ A critical part of drug trials is cardiac toxicity or the effect of drugs on an existing heart condition. Under normal circumstances, the stem cells would metabolize and differentiate at various levels in the body. Exposure to toxins, might interfere with the production of molecules and therefore the intercellular connectivity and the process of differentiation. The CEPA panel is the prime assessing body involved in investigation of such use of the stem cells.
Exposure to a suitable diet or habit form can be the criteria of concern after a successful stem cell therapy procedure. A recent study stated that exposure to nicotine could inflict a harm on the recently infiltrated mesenchymal stem cells by interfering with their proliferation and differentiation potential. Nicotine can be an essential part of a smoker’s life. For evaluation purposes, culture media containing MSCs were exposed to meagre concentrations of nicotine. Physiologically, this evaluation could be equalized with the exposure of recently infiltrated stem cells in a chronic smoker. The foremost effect witnessed on stem cells after an observational period of 7 days under the effect of nicotine was of the abject proliferation rate. A further observation to rule out the use of nicotine was the alteration in gene expression of PTK2 and RUNX2. These genes are primarily associated with the differentiation process of osteoblasts and with the migration of the same. To conclude, whether it is the option of nanoclay-reinforced hydrogel or a standard stem cell transplant that the patient opts for, the results could only prove to be satisfying if the patient observed an abstinence from use of nicotine. It is important to site here that if the patent is a non-smoker, the detrimental effect of nicotine could make its way to the stem cells if they stay close to people who were regular in the use of nicotine in any form. Common food items that contain nicotine are eggplant, green tomatoes, cauliflower and potato.
Before the release of stem cells to the health facilities, there are a couple of aspects of the stem cell that scientists are supposed to confirm such as:
The appearance of the specialized stem cell: The deliberative gene expression in the culture media can be essential in affirming characteristics of the resultant, specialized stem cells. During the cultivation of stem cells, there are some observations that can determine the level of gene expression. For instance, if its a neural cell that the stem cells are supposed to be specialized into, then have the same set of genes that control the neurons in the brain been expressed in the culture media? Based on the functionality of every cell in the body, even stem cells are expected to own a certain form that matches with that of the original cell. Like for instance, the stem cells specialized to be neural stem cells would be expected to bear a close resemblance to the shape of the neurons or nerve cells with slender ends that actuate the process of signal transmission within the brain.
The condition of the specialized stem cell: The specialize stem cells are expected to own the same level propriety as the original cell forms. For example, a cardiac cell contracts and relaxes at regular intervals to keep the flow of the blood smoothly running in various chambers of the heart. A random search by experiments in the lab can assure the same level of functionality and accuracy in a specialized, cardiac stem cell. Scientists can affirm the contraction and relaxation of cardiac stem cells by observing the plate of culture media under a microscope.
The safety asset linked with the specialized stem cell: When the stem cells are being grown with the prime purpose of therapy, it is unconflicted to assess the safety of their use. The cautionary use of a specialized cell would also involve the loss of a fully-differentiated stem cell to further differentiate into any other cell form. Teratoma is a hazard that might result if undifferentiated instead of a specialized stem cell was used in a therapy. Teratomas are an undefined aggregate of various cell forms and therefore a tumour. So, the loss of further differentiation is an aspect of stem cells that needs to be affirmed by the scientists to acknowledge the absence of teratomas after stem cell infiltration.
