This study found that ionizing radiation primarily affects keratinocyte stem cells in the hair follicle, suggesting they play a central role in radiation-induced hair graying, rather than melanocyte stem cells.

This study reports that in aged mice, hair follicle dermal stem cells exhibit diminished self-renewal and preferential differentiation into dermal sheath cells, contributing to age-related hair loss.

This study found that Dab2 conditional knockout mice experienced delayed hair follicle cycles and reduced hair follicle stem cell activity, suggesting Dab2's crucial role in regulating stem cell activation and anti-aging process in hair follicles.

This study established a new in vitro culture system that supports the growth and dynamic self-organization of hair follicle stem cells and their progeny, promoting a stable population equilibrium.

This review discusses current knowledge of keratinocyte stem cell dynamics, including their regenerative roles and potential applications beyond wound healing, but presents no new clinical findings.
