This study found that direct interactions between human dermal papilla cells and melanocytes under low oxygen conditions improved cell functions and could be important for hair regeneration efforts.

In this study, researchers identified a new dominant mutation in Hairless mice, called Pied, resulting from a deletion in the Adam10 gene, which causes freckle-like skin pigmentation by inhibiting melanocyte expansion.

This study found that the cell of origin in mouse skin affects melanoma phenotype and response to therapies, despite the presence of the same genetic mutations.

In this study using genetic mouse models, researchers discovered that senescent melanocytes in nevi secrete osteopontin, which activates hair stem cells, enhancing hair growth; this process is mirrored in human hairy nevi, suggesting a potential therapeutic target for regenerative disorders.

This study explored the diversity of melanocyte stem cell subpopulations in the hair follicles of adult female mice and identified novel groups with distinct immune privilege regulation, suggesting a heterogeneous landscape that future research should consider.
