Bone marrow mesenchymal stem cells (BM-MSCs) are used to repair hypoxic or ischemic tissue. After hypoxic the level of ATP is decreases, cellular functions do not continue and apoptosis or necrosis occur. Apoptosis is a progress of programmed cell death that occurs in normal or pathological conditions. In this study, we were investigated the hypoxic effect on apoptosis in mesenchymal stem cell. Bone marrow-derived stem cells were cultured in hypoxic (1% or 3%) or normoxic conditions 24, 96 well plates for 36 h. Cell viability was shown by MTT assay on 36 h. After fixation of cells with 4% paraformaldehyde, distributions of caspase-3, Bcl-2 and Bax with indirect immunoperoxidase technique, apoptotic cells with TUNEL assay were investigated. All staining results were evaluated using H-score analyses method with ANOVA, statistically. As a result, hypoxic condition was toxic for human mesenchymal stem cells and the number of death cell was higher in that than normoxic condition.

Background Multiple sclerosis is an inflammatory, neurodegenerative disease of the central nervous system for which therapeutic mesenchymal stem cell transplantation is under study. Published experience of culture-expanding multiple sclerosis patients’ mesenchymal stem cells for clinical trials is limited. Objective To determine the feasibility of culture-expanding multiple sclerosis patients’ mesenchymal stem cells for clinical use. Methods In a phase I trial, autologous, bone marrow-derived mesenchymal stem cells were isolated from 25 trial participants with multiple sclerosis and eight matched controls, and culture-expanded to a target single dose of 1–2 × 106 cells/kg. Viability, cell product identity and sterility were assessed prior to infusion. Cytogenetic stability was assessed by single nucleotide polymorphism analysis of mesenchymal stem cells from 18 multiple sclerosis patients and five controls. Results One patient failed screening. Mesenchymal stem cell culture expansion was successful for 24 of 25 multiple sclerosis patients and six of eight controls. The target dose was achieved in 16–62 days, requiring two to three cell passages. Growth rate and culture success did not correlate with demographic or multiple sclerosis disease characteristics. Cytogenetic studies identified changes on one chromosome of one control (4.3%) after extended time in culture. Conclusion Culture expansion of mesenchymal stem cells from multiple sclerosis patients as donors is feasible. However, culture time should be minimized for cell products designated for therapeutic administration.

ABSTRACTMesenchymal stem cells are one of the promising tissue specific stem cell source for neural tissue regeneration applications. Previous studies on human mesenchymal stem cell (hMSC) derived neurons have been limited and not statisfactory in terms of neuronal activity. In this study, we analysed the functionality of bone marrow hMSCs differentiated into neural protein expressing cells by a single step cytokine based induction protocol. Neurons from both primary hMSCs and hMSC cell line displayed spontaneous activity (≥75%) as demonstrated by Ca++ imaging. Furthermore, when electrically stimulated, hMSC induced neurons (hMd-Neuron) matched the response of a typical neuron in the process of maturation. Our results reveal that enriched neurothrophic factors enhance differentiation capacity of bone marrow hMSCs into high yielding functional neurons with spontaneous activity and mature into electrophysiologically active state. hMd-Neurons have the potential to be used as a tool for disease modelling of neuropathologies and neural differentiation studies.

Background: Osteochondral lesions are a common clinical problem and their management has been historically challenging. Mesenchymal stem cells have the potential to differentiate into chondrocytes and thus restore hyaline cartilage to the defect, theoretically improving clincal outcomes in these patients. They can also be harvested with minimal donor site morbidity. Purpose: To assess the clinical and functional outcomes of mesenchymal stem cell implantation to treat isolated osteochondral defects of the knee. A secondary purpose is to assess the quality of the current available evidence as well as the radiological and histological outcomes. We also reviewed the cellular preparation and operative techniques for implantation. Study Design: Systematic review. Methods: A comprehensive literature search of 4 databases was carried out: CINAHL, Embase, MEDLINE, and PubMed. We searched for clinical studies reporting the outcomes on a minimum of 5 patients with at least 12 months of follow-up. Clinical, radiological, and histological outcomes were recorded. We also recorded demographics, stem cell source, culture technique, and operative technique. Methodological quality of each study was assessed using the modified Coleman methodology score, and risk of bias for the randomized controlled studies was assessed using the Cochrane Collaboration tool. Results: Seventeen studies were found, encompassing 367 patients. The mean patient age was 35.1 years. Bone marrow was the most common source of stem cells utilized. Mesenchymal stem cell therapy consistently demonstrated good short- to medium-term outcomes in the studies reviewed with no serious adverse events being recorded. There was significant heterogeneity in cell harvesting and preparation as well as in the reporting of outcomes. Conclusion: Mesenchymal stem cells demonstrated a clinically relevant improvement in outcomes in patients with osteochondral defects of the knee. More research is needed to establish an optimal treatment protocol, long-term outcomes, and superiority over other therapies. Registration: CRD42020179391 (PROSPERO).
