One theory of ageing suggests that between the ages of 30 and 50, our stem cells reach a turning point and start to decline in number and function. This results in the typical features associated with ageing.
What is stem cell therapy?
Stem cell-based therapies are defined as any treatment for a disease or a medical condition that fundamentally involves the use of any type of viable human stem cells including embryonic stem cells (ESCs), iPSCs and adult stem cells for autologous and allogeneic therapies (8). Stem cells offer the perfect solution when there is a need for tissue and organ transplantation through their ability to differentiate into the specific cell types that are required for repair of diseased tissues.
What are the ethical issues faced by stem cell therapy?
Stem cell-based therapies face many obstacles that need to be urgently addressed. The most persistent concern is the ethical conflict regarding the use of ESCs. As previously mentioned, ESCs are far superior regarding their potency; however, their derivation requires destruction human embryos. True, the discovery of iPSCs overcame this concern; nevertheless, iPSCs themselves currently face another ethical controversy of their own which addresses their unlimited capacity of differentiation with concerns that these cells could one day be applied in human cloning. The use of iPSCs in therapy is still considered a high-risk treatment modality, since transplantation of these cells could induce tumor formation. Such challenge is currently addressed through developing optimized protocols to ensure their safety in addition to developing global clinical-grade iPSCs cell lines before these cells are available for clinical use (61). As for MSCs, these cells have been universally considered safe, however continuous monitoring and prolonged follow-up should be the focus of future research to avoid the possibility of tumor formation after treatments (62). Finally, it could be postulated that one of the most challenging ethical issues faced in the field of stem cell-based therapies at the moment, is the increasing number of clinics offering unproven stem cell-based treatments. Researchers are thus morally obligated to ensure that ethical considerations are not undermined in pursuit of progress in clinical translation.
Why is translational research important?
The importance of translational research lies in it’s a role as a filter to ensure that only safe and effective therapies reach the clinic (23). It bridges the gap from bench to bed. Currently, some stem cell-based therapies utilizing adult stem cells are clinically available and mainly include bone marrow transplants of hematopoietic stem cells and skin grafts for severe burns (23). To date, there are more than 3,000 trials involving the use of adult stem cells registered in WHO International Clinical Trials Registry. Additionally, initial trials involving the new and appealing iPSCs based therapies are also registered. In fact, the first clinical attempt employing iPSCs reported successful results in treating macular degeneration (24). Given the relative immaturity in the field of cellular therapy, the outcomes of such trials shall facilitate the understanding of the timeframes needed to achieve successful therapies and help in better understanding of the diseases. However, it is noteworthy that evaluation of stem cell-based therapies is not an easy task since transplantation of cells is ectopic and may result in tumor formation and other complications. This accounts for the variations in the results reported from previous reports. The following section discusses the published data of some of the most important clinical trials involving the use of different types of stem cells both in medicine and in dentistry.
Why are beta cells destructed?
Pancreatic beta cells are destructed in type 1 diabetes mellitus, because of disorders in the immune system while in type 2 insulin insufficiency is caused by failure of the beta-cell to normally produce insulin. In both cases the affected cell is the beta cell, and since the pancreas does not efficiently regenerate islets from endogenous adult stem cells, other cell sources were tested (38). Pluripotent stem cells (PSCs) are considered the cells of choice for beta cell replacement strategies (39). Currently, there are a few industry-sponsored clinical trials that are registered targeting beta cell replacement using ESCs. These trials revolve around the engraftment of insulin-producing beta cells in an encapsulating device subcutaneously to protect the cells from autoimmunity in patients with type 1 diabetes (40). The company ViaCyteTMin California recently initiated a phase I/II trial ({"type":"clinical-trial","attrs":{"text":"NCT02239354","term_id":"NCT02239354"}}NCT02239354) in 2014 in collaboration with Harvard University. This trial involves 40 patients and employs two subcutaneous capsules of insulin producing beta cells generated from ESCs. The results shall be interesting due to the ease of monitoring and recovery of the transplanted cells. The preclinical studies preceding this trial demonstrated successful glycemic correction and the devices were successfully retrieved after 174 days and contained viable insulin-producing cells (41).
What is cell based therapy?
Cell-based therapy as a modality of regenerative medicine is considered one of the most promising disciplines in the fields of modern science & medicine. Such an advanced technology offers endless possibilities for transformative and potentially curative treatments for some of humanities most life threatening diseases. Regenerative medicine is rapidly becoming the next big thing in health care with the particular aim of repairing and possibly replacing diseased cells, tissues or organs and eventually retrieving normal function. Fortunately, the prospect of regenerative medicine as an alternative to conventional drug-based therapies is becoming a tangible reality by the day owing to the vigorous commitment of the research communities in studying the potential applications across a wide range of diseases like neurodegenerative diseases and diabetes, among many others (1).
Can stem cells be used in dentistry?
Some of these trials resulted in remarkable impact on various diseases. In this review, the advances and challenges for the development of stem-cell-based therapies are described, with focus on the use of stem cells in dentistry in addition to the advances reached in regenerative treatment modalities in several diseases. The limitations of these treatments and ongoing challenges in the field are also discussed while shedding light on the ethical and regulatory challenges in translating autologous stem cell-based interventions, into safe and effective therapies.
Is stem cell therapy safe?
Leading countries in the field have devised guidelines serving that purpose. Recently, the Food and Drug Administration (FDA) has released regulatory guidelines to ensure that these treatments are safe and effective (59). These guidelines state that; treatments involving stem cells that have been minimally manipulated and are intended for homogeneous use do not require premarket approval to come into action and shall only be subjected to regulatory guidelines against disease transmission. In 2014, a radical regulatory reform in Japan occurred with the passing of two new laws that permitted conditional approval of cell-based treatments following early phase clinical trials on the condition that clinical safety data are provided from at least ten patients. These laws allow skipping most of the traditional criteria of clinical trials in what was described as “fast track approvals” and treatments were classified according to risk (60). To date, the treatments that acquired conditional approval include those targeting; spinal-cord injury, cardiac disease and limb ischemia (61). Finally, regulatory authorities are now demanding application of standardization and safety regulations protocols for cellular products, which include the use of Xeno-free culture media, recombinant growth factors in addition to “Good Manufacturing Practice” (GMP) culture supplies.
What is the FDA's response to stem cell products?
