September 2023 in “Cells tissues organs” In this study, researchers observed that in mice, as they age beyond 200 days, unusual curved hair follicles and increased white hairs emerge, indicating stem cell-related changes in keratinocyte and melanocyte characteristics, providing insights into hair aging processes.
In this study, researchers explored the heterogeneity of pigment cells in the human scalp anagen hair follicle bulb and discovered unexpected subpopulations of melanocytes, including immature SOX10-negative cells, highlighting potential non-melanogenic roles or transitional migratory functions that require further investigation.
