Cardiovascular disease (CVD) is the leading cause of death globally. Current treatment options include lifestyle changes, medication, and surgical intervention. However, many patients are unsuitable candidates for surgeries due to comorbidities, diffuse coronary artery disease or advanced stages of heart failure. The search for new treatment options has recently transitioned from cell-based therapies to stem-cell derived extracellular vesicles (EVs). A number of challenges remain in the EV field, including the effect of comorbidities, characterization, and delivery, However, recent revolutionary developments and insight into the potential of 'personalizing' EV contents by bioengineering methods to alter specific signaling pathways in the ischemic myocardium hold promise. Here, we discuss the past limitations of cell-based therapies, and recent EV studies involving in vivo, in vitro, and omics, and future challenges and opportunities in EV-based treatments in CVD.

The incidence of cardiovascular disease (CVD) in adults are increasing worldwide with impaired repair mechanisms, leading to tissue and organ failure. With the current advancements, life expectancy has improved and has led to search for new treatment strategies that improves tissue regeneration. Recently, stem cell therapy and tissue engineering has captured the attention of clinicians, scientists, and patients as alternative treatment options. The overall clinical experience of these suggests that they can be safely used in the right clinical setting. Ultimately, large outcome trials will have to be conducted to assess their efficacy. Clinical trials have to be carefully designed and patient safety must remain the key concern. At the same time, continued basic research is required to understand the underlying mechanism of cell-based therapies and cell tissue interactions. This chapter reviews the evolving paradigm of stem cell therapy and tissue engineering approaches for clinical application and explores its implications.

Stroke remains a devastating disease with limited treatment options, despite our growing understanding of its pathology. While ischemic stroke is traditionally characterized by a blockage of blood flow to the brain, this may coincide with reduced blood circulation to the eye, resulting in retinal ischemia, which may in turn lead to visual impairment. Although effective treatment options for retinal ischemia are similarly scarce, new evidence suggests that deleterious changes to mitochondrial structure and function play a major role in both cerebral and retinal ischemia pathologies. Prior studies establish that astrocytes transfer healthy mitochondria to ischemic neurons following stroke; however, this alone is not enough to significantly mitigate the damage caused by primary and secondary cell death. Thus, stem cell-based regenerative medicine targeting amelioration of ischemia-induced mitochondrial dysfunction via the transfer of functional mitochondria to injured neural cells represents a promising approach to improve stroke outcomes for both cerebral and retinal ischemia. In this review, we evaluate recent laboratory evidence supporting the remedial capabilities of mitochondrial transfer as an innovative stroke treatment. In particular, we examine exogenous stem cell transplants in their potential role as suppliers of healthy mitochondria to neurons, brain endothelial cells, and retinal cells. Impact statement Stroke constitutes a global health crisis, yet potent, applicable therapeutic options remain effectively inaccessible for many patients. To this end, stem cell transplants stand as a promising stroke treatment and as an emerging subject of research for cell-based regenerative medicine. This is the first review to synthesize the implications of stem cell-derived mitochondrial transfer in both the brain and the eye. As such, this report carries fresh insight into the commonalities between the two stroke-affected organs. We present the findings of this developing area of research inquiry with the hope that our evaluation may advance the use of stem cell transplants as viable therapeutic alternatives for ischemic stroke and related disorders characterized by mitochondrial dysfunction. Such lab-to-clinic translational advancement has the potential to save and improve the ever increasing millions of lives affected by stroke.

Abstract Studies of the regenerating hematopoietic system have led to the definition of many of the fundamental principles of stem cell biology. Therapies based on a range of tissue stem cells have been widely touted as a new treatment modality, presaging an emerging new specialty called regenerative medicine that promises to harness stem cells from embryonic and somatic sources to provide replacement cell therapies for genetic, malignant, and degenerative conditions. Insights borne from stem cell biology also portend development of protein and small molecule therapeutics that act on endogenous stem cells to promote repair and regeneration. Much of the newfound enthusiasm for regenerative medicine stems from the hope that advances in the laboratory will be followed soon thereafter by breakthrough treatments in the clinic. But how does one sort through the hype to judge the true promise? Are stem cell biologists and the media building expectations that cannot be met? Which diseases can be treated, and when can we expect success? In this review, we outline the realms of investigation that are capturing the most attention, and consider the current state of scientific understanding and controversy regarding the properties of embryonic and somatic (adult) stem cells. Our objective is to provide a framework for appreciating the promise while at the same time understanding the challenges behind translating fundamental stem cell biology into novel clinical therapies.

Stem cells represent a new treatment option in medicine and pharmacy. Stem cells have been increasingly used for the treatment of many diseases. In fact, they have spurred a new age of medicine called regenerative medicine. In recent years, regenerative medicine has become a new revolution in disease treatment, especially with the use of stem cell drugs. Stem cell drugs refer to live stem cell based products that used as drugs for particular diseases. Unlike autologous stem cell transplantation, stem cell drugs are “off-the-shelf” products that are ready to be used without requirement of any further manipulation. This review aims to summarize some of the approved stem cell drugs, and discuss the revolution of regenerative medicine and personalized medicine. As well, the review will discuss how stem cell drugs have led to a new direction in stem cell therapy, providing a new platform for patient needs.

Stem cell technology and its application in regenerative medicine is the future gateway for the treatment of most non-communicable diseases (NCDs). As the burden of NCDs continues to rises globally, regenerating the cells, tissues and organs will be the mainstream treatment option. The world is prepared for this intriguing but promising avenue of biomedical technology and medicine but Africa is grossly lagging far behind. African governments, universities, research and health institutions need to take a leading role in empowering and mainstreaming stem cell research.  Moreover, for Africa, there is a huge potential for translating stem cell technology into clinical treatments due to the fact that there are limited treatment options for life-threatening forms of NCDs.  Some African countries have well-developed stem cell facilities and large-scale stem cell therapy centers. The use of adult stem cells in liver failure, diabetes and cardiac infarcts has shown success in some African countries. The present work reviews the status, potential and future prospects of stem cell technology and regenerative medicine in Tanzania with particular emphasis on the adult stem cells applicability into the immediate use inpatient care.  The paper also reviews the available cell identification systems and markers and moral and ethical aspects of stem cell science necessary in the translational treatment regimens.

Abstract Background Although originator biologics are effective therapies for patients with ulcerative colitis (UC), they can be costly and may not be widely available. Therefore, less expensive biosimilars have been developed and approved to treat and manage symptoms. In this new treatment landscape, UC-treatment preferences are unknown. Thus, this interim analysis aimed to characterise physician preferences for biologics for the treatment of UC in France, Germany and the UK. Methods As part of a broader chart review study, treatment preferences were also collected from participating gastroenterologists and general practitioners (GPs) in France, Germany and the UK who had treated patients (≥ 18 years) with moderate-to-severe UC who had received ≥ 1 UC-related biologic any time from 2014 to 25 October 2019. Descriptive statistics were used to describe the sample overall, and by physician speciality and treatment preference. Results Physicians (161 gastroenterologists; 57 GPs) were from different clinical settings in France (39.9%), Germany (28.4%) and the UK (31.7%). Overall, infliximab (33.0%) and adalimumab (32.1%) were selected more often as first treatment options than their biosimilars (17.0% and 9.6%, respectively). Gastroenterologists preferred biosimilars more frequently than GPs did (35.4% vs. 1.8%). More physicians who preferred biosimilars were from France (48.3%) than Germany (17.2%) or the UK (34.5%). In France and the UK, 93.8% of physicians who selected biosimilars worked in hospital settings; in Germany, 50.0% worked in clinics and 50.0% worked in practice settings with statutory and private patients. Physicians who preferred biosimilars treated more patients with UC in the preceding 12 months than those who preferred originators did (mean ± SD: 110.3 ± 113.9 vs. 94.0 ± 93.2). Although most physicians reported efficacy as a reason for biologic preference (93.6%), physicians who preferred originators were more likely to report good tolerability (73.8%) and patient preference (20.6%) and less likely to report affordability or availability (11.9%) than physicians who preferred biosimilars (63.8%, 10.3% and 44.8%, respectively). In patients who failed anti-TNF therapy, vedolizumab was the preferred treatment (78.9%), although this preference differed by speciality (gastroenterologists: 83.2%; GPs: 66.7%). Conclusion Originator biologics for treating patients with moderate-to-severe UC dominate the treatment landscape in Europe, driven primarily by efficacy, tolerability and patient preference. However, variations and differences in preferences by speciality and clinical setting may suggest a need to explore additional treatment options to manage disease symptoms among patients with UC.
