Abstract

Human bone marrow-derived mesenchymal stem cells (hMSCs) are a population of pluripotent cells. They can differentiate into different embryonic layer cells as osteoblasts, adipocytes, chondrocytes, myoblasts, neurocytes, etc. However, there are only few reports with regard to differentiate hMSCs into epidermal cells in vitro. In this study, we want to investigate the feasibility of inducing hMSCs into epidermal-like cells under specific medium in vitro. hMSCs in specific inducing medium expressed the early markers of epidermal cell lineage, P63, cytokeratin19 (CK19), the late differentiated marker, the pan-cytokeratin, and another early marker, the beta1-integrin, which up-regulated remarkably in inducing medium. Their morphologies were changed from spindle-like fibroblastic appearances to oblate or irregular shapes under phase contrast microscopy. The hemidesmosome structure was found using the transmission electron microscope. All these data suggested that, under certain conditions, hMSCs have the potential to differentiate into epidermal-like cells. It will be of great accordance in the study of the multipotential property of hMSCs.
