“Jekyll and Hyde” refers to persons with an unpredictably dual personality, who are battling between good and evil within themselves In this regard, even cells consist of good and evil counterparts. Normal stem cells (NSCs) and cancer stem cells (CSCs) are two types of cells that share some similar characteristics but have distinct functions that play a major role in physiological and pathophysiological development. In reality, NSCs such as the adult and embryonic stem cells, are the good cells and the ultimate treatment used in cell therapy. CSCs are the corrupted cells that are a subpopulation of cancer cells within the cancer microenvironment that grow into a massive tumour or malignancy that needs to be treated. Hence, understanding the connection between NSCs and CSCs is important not just in cancer development but also in their therapeutic implication, which is the focus of this review.

Stem cells have been used for regenerative and therapeutic purposes in a variety of diseases. In ischemic brain injury, preclinical studies have been promising, but have failed to translate results to clinical trials. We aimed to explore the application of stem cells after ischemic brain injury by focusing on topics such as delivery routes, regeneration efficacy, adverse effects, and in vivo potential optimization. PUBMED and Web of Science were searched for the latest studies examining stem cell therapy applications in ischemic brain injury, particularly after stroke or cardiac arrest, with a focus on studies addressing delivery optimization, stem cell type comparison, or translational aspects. Other studies providing further understanding or potential contributions to ischemic brain injury treatment were also included. Multiple stem cell types have been investigated in ischemic brain injury treatment, with a strong literature base in the treatment of stroke. Studies have suggested that stem cell administration after ischemic brain injury exerts paracrine effects via growth factor release, blood-brain barrier integrity protection, and allows for exosome release for ischemic injury mitigation. To date, limited studies have investigated these therapeutic mechanisms in the setting of cardiac arrest or therapeutic hypothermia. Several delivery modalities are available, each with limitations regarding invasiveness and safety outcomes. Intranasal delivery presents a potentially improved mechanism, and hypoxic conditioning offers a potential stem cell therapy optimization strategy for ischemic brain injury. The use of stem cells to treat ischemic brain injury in clinical trials is in its early phase; however, increasing preclinical evidence suggests that stem cells can contribute to the down-regulation of inflammatory phenotypes and regeneration following injury. The safety and the tolerability profile of stem cells have been confirmed, and their potent therapeutic effects make them powerful therapeutic agents for ischemic brain injury patients.

Heart failure (HF) is one of the leading death causes in patients with myocardial infarction (MI). The modern methods of reperfusion MI therapy, such as thrombolysis, surgery and balloon revascularization, even when performed early, could fail to prevent the development of large myocardial damage zones, followed by HF. Therefore, the researches have been searching for the methods which improve functional status of damaged myocardium. This review is focused on stem cell therapy, a method aimed at cardiac function restoration. The results of experimental and clinical studies on stem cell therapy in coronary heart disease are presented. Various types of stem cells, used for cellular cardiomyoplasty, are characterised. The methods of cell transplantation into myocardium and potential adverse effects of stem cell therapy are discussed.

The subepithelial intestinal myofibroblast is an important cell orchestrating many diverse functions in the intestine and is involved in growth and repair, tumorigenesis, inflammation, and fibrosis. The myofibroblast is but one of several α-smooth muscle actin-positive (α-SMA+) mesenchymal cells present within the intestinal lamina propria, including vascular pericytes, bone marrow-derived stem cells (mesenchymal stem cells or hematopoietic stem cells), muscularis mucosae, and the lymphatic pericytes (colon) and organized smooth muscle (small intestine) associated with the lymphatic lacteals. These other mesenchymal cells perform many of the functions previously attributed to subepithelial myofibroblasts. This review discusses the definition of a myofibroblast and reconsiders whether the α-SMA+ subepithelial cells in the intestine are myofibroblasts or other types of mesenchymal cells, i.e., pericytes. Current information about specific, or not so specific, molecular markers of lamina propria mesenchymal cells is reviewed, as well as the origins of intestinal myofibroblasts and pericytes in the intestinal lamina propria and their replenishment after injury. Current concepts and research on stem cell therapy for intestinal inflammation are summarized. Information about the stem cell origin of intestinal stromal cells may inform future stem cell therapies to treat human inflammatory bowel disease (IBD).

Stem cell therapy is an approach to use cells that have the ability of self-renewal and to differentiate into different types of functional cells that are obtained from embryo and other postnatal sources to treat multiple disorders. These cells can be differentiated into different types of stem cells based on their specific characteristics to be totipotent, unipotent, multipotent or pluripotent. As potential therapy, pluripotent stem cells are considered to be the most interesting as they can be differentiated into different type of cells with similar characteristics as embryonic stem cells. Induced pluripotent stem cells (iPSCs) are adult cells that are reprogrammed genetically into stem cells from human fibroblasts through expressing genes and transcription factors at different time intervals. In this review, we will discuss the applications of stem cell therapy using iPSCs technology in treating neurodegenerative disorder such that Alzheimer’s disease (AD), Parkinson’s disease (PD), and Amyotrophic Lateral Sclerosis (ALS). We have also broadly highlighted the significance of pluripotent stem cells in stem cell therapy.

Introduction: Stem cell therapy (SCT) has been proposed for the treatment of neurological disorders. Although there isinsufficient clinical evidence to support its efficacy, unproven SCTs are being performed worldwide. Hypothesis: In this study, we investigated the perspectives and expectations of chronic ischemic stroke patients and physicians about SCTs. Methods: A total of 250 chronic ischemic stroke patients were interviewed at 4 hospitals. Structured open and closed questions about SCT for chronic stroke were asked by trained interviewers using the conventional in-person method. In addition, 250 stroke-related physicians were randomly interviewed via an e-mail questionnaire. Results: Of the 250 patients (mean 63 years, 70% male), 121 (46%) responded that they wanted to receive SCT in spite of its unknown side effects. Around 60% of the patients anticipated physical, emotional, and psychological improvement after SCT, and 158 (63%) believed that SCT might prevent strokes. However, physicians had much lower expectations about the effectiveness of SCTs, which was not in line with patient expectations. Multivariate analysis revealed that male gender (OR: 2.00, 95% CI: 1.10-3.64), longer disease duration (OR: 1.01, 95% CI:1.00-1.02), higher modified Rankin Scale score (OR: 1.30, 95% CI 1.06-1.60), and familiarity with stem cells (OR: 1.86, 95% CI: 1.10-3.15) were independently associated with wanting SCT. The major source of information about SCT was television (68%), and the most reliable source was physicians (49%). Conclusion: Patients have unfounded expectations that SCT will improve their functioning. Considering our finding that the major source of information on stem cells is media channels but not the physician, to decrease patients’ inappropriate exposure, doctors should make more effort to educate patients using mass media with accurate information.
