In this laboratory study, the researchers found that combining dermal papilla cell-derived exosomes with collagenous sequences significantly enhanced hair follicle stem cell migration and proliferation, highlighting a potential strategy for hair regeneration through modulation of the hsa-novel-238a-CASP9 axis.

This study found that human umbilical cord mesenchymal stem cells (hUCMSCs) promoted hair regeneration in androgenetic alopecia model mice by activating Wnt/β-catenin signaling, enhancing hair follicle stem cell proliferation, and reducing dermal papilla cell apoptosis.

This study found that mice lacking REDD1 experienced an expansion of dermal white adipose tissue through both hypertrophy and hyperplasia, suggesting a potential therapeutic target for skin adipogenesis regulation.

This study found that BMP2 increased PTEN expression and induced autophagy, promoting hair follicle stem cell differentiation in both in vitro models and a mouse wound model.

This study found that stimulating dermal papilla cells with specific adipo-osteogenic factors and growth factors helped maintain their viability and restored their hair-forming activity in vitro.

This study discovered that exosomes from adipose-derived mesenchymal stem cells can mitigate damage in dermal papilla cells by modulating the TGF-β1/SMAD2 signaling pathway through miRNAs miR-574-3p and miR-125a-5p, revealing potential therapeutic targets for androgenetic alopecia.

In this study, mouse hair follicle stem cells cultured in mouse embryonic fibroblast/keratinocyte serum-free medium exhibited the highest proliferative ability and stronger osteogenic differentiation potential, similar to hair follicle dermal papilla cells.
