Induced pluripotent stem cell-derived mesenchymal stem cells: whether they can become new stars of cell therapy

Stem cell therapy constitutes a pivotal subject in contemporary discourse, with donor stem cells having been employed in research and clinical treatments for several decades. Primary cell transplantation encompasses diverse stem cell types, including ectomesenchymal stem cells, hematopoietic stem cells, and various stem cell derivatives such as vesicles and extracellular vesicles. Nevertheless, the emergence of cell engineering techniques has heralded a new epoch in stem cell therapy, markedly broadening their therapeutic potential. Induced pluripotent stem cells (iPSCs) epitomize a significant milestone in modern medical biology. This groundbreaking discovery offers significant potential in disciplines such as biology, pathophysiology, and cellular regenerative medicine. As a result, iPSCs derived differentiated cells have become a pioneering avenue for cell therapy research. Induced mesenchymal stem cells (iMSCs), derived from iPSCs, represent a novel frontier in MSCs related research. Empirical evidence suggests that iMSCs demonstrate enhanced proliferative capacities compared to natural MSCs, with diminished age-related variability and heterogeneity. Numerous clinical trials have highlighted the prospective superiority of iMSCs. This article synthesizes current basic research and clinical trials pertaining to iMSCs, aiming to provide a reference point for future research endeavors.
