Background/aim: Peripheral neurotoxicity is a dose-limiting factor of many chemotherapeutic agents, including cisplatin. Mesenchymal stem cells are promising for the treatment of several neurological disorders, and our aim was to verify the neuroprotective potential of human mesenchymal stem cells (hMSCs) on dorsal root ganglia (DRG) exposed to cisplatin.
Materials And Methods: DRG were exposed to different cisplatin concentrations and then co-cultured with hMSCs or with hMSC-conditioned medium.
Results: hMSCs showed a neuroprotective effect on cisplatin-induced death of DRG, mediated by direct contact. Moreover, DRG exhibited an MSC-dependent promotion of neurite outgrowth, in particular at early time points. For this effect, the expression of Neurite Outgrowth Inhibitor (NOGO) and Myelin Associated Glycoprotein (MAG) by hMSCs was pivotal.
Conclusion: hMSCs are a promising tool for reducing the neurotoxic effect of cisplatin.

The December 2024 US Food and Drug Administration (FDA) approval of Mesoblast's Ryoncil (remestemcel-L-rknd)-allogeneic bone marrow mesenchymal stromal cell (MSC(M)) therapy-in pediatric acute steroid-refractory graft-versus-host-disease finally ended a long-lasting drought on approved MSC clinical products in the United States. While other jurisdictions-including Europe, Japan, India, and South Korea-have marketed autologous or allogeneic MSC products, the United States has lagged in its approval. The sponsor's significant efforts and investments, working closely with the FDA addressing concerns regarding clinical efficacy and consistent MSC potency through an iterative process that spanned several years, was rewarded with this landmark approval.

Background: Pathogenic or null mutations in WRN helicase is a cause of premature aging disease Werner syndrome (WS). WRN is known to protect somatic cells including adult stem cells from premature senescence. Loss of WRN in mesenchymal stem cells (MSCs) not only drives the cells to premature senescence but also significantly impairs the function of the stem cells in tissue repair or regeneration.

Introduction: Periodontal diseases are prevalent among middle-aged and elderly individuals. There's still no satisfactory solution for tooth loss caused by periodontal diseases. Human periodontal ligament stem cells (hPDLSCs) is a distinctive subgroup of mesenchymal stem cells, which play a crucial role in periodontal supportive tissues, but their application value hasn't been fully explored yet.

Epiregulin plays a role in a range of biological activities including malignancies. This study aims to investigate the potential contribution of epiregulin to bone cell differentiation and bone homeostasis. The data showed that epiregulin expression was upregulated during osteogenesis but downregulated during adipogenesis.

Phytochemicals, which are bioactive compounds contained in fruits, vegetables, and teas, have a positive effect on human health by having anti-inflammatory, antioxidant, and anticarcinogenic effects. Several studies have highlighted the ability of bioactive compounds to activate key cellular enzymes associated with important signaling pathways related to cell division and proliferation, as well as their role in inflammatory and immunological responses. Some phytochemicals are associated with increased proliferation, differentiation, and expression of markers related to osteogenesis, bone formation, and mineralization by activating various signaling pathways.
