Dermal exosomes with miR-218-5p boost hair growth by controlling β-catenin signaling.

This study demonstrated that a device combining hyaluronic acid-based dissolving microneedles and lipid polymer hybrid nanoparticles effectively delivered miR-218 to promote hair growth in a shaved mouse model, outperforming topical smear treatment without safety concerns.

This study suggests that early-stage dermal papilla cell-derived exosomes may enhance adipose stem cells' hair inductive abilities through specific miRNAs.

In this study, researchers found that hTERT/SV40 immortalization of human dermal fibroblasts up-regulates skin cell markers and highlights the SIRT1 and miR-93 pathways' roles in maintaining fibroblast proliferation, potentially benefiting developments in the cosmetic industry.

This study found that UVB radiation significantly alters miRNA expression and induces cytotoxicity and apoptosis in normal human dermal papilla cells.
