This study compares the properties of hair follicle dermal papilla cells (HFDPCs) and human dermal stem/progenitor cells (hDSPCs), both types of adult stem cells (ASCs) with potential for tissue regeneration. hDSPCs exhibit greater cell division and differentiation capacity into adipocytes, chondrocytes, and osteoblasts than HFDPCs. Conversely, HFDPCs show higher expression of markers related to hair regeneration, such as SOX2 and S100β. Protein kinase assays reveal significant changes in the phosphorylation of ERK1/2, c-JUN, CREB, YES, and GSK3α/β in both cell types compared to dermal fibroblasts, which may explain their differing properties. These findings suggest that the unique characteristics of each ASC type could influence their therapeutic applications.
