This review discusses recent advances in understanding hair follicle stem cell dynamics and interactions, but it reports no new experimental findings.

Cylindromas likely originate from hair follicle stem cells, not sweat glands.

The study suggests that immune privilege collapse in bulge cells and the involvement of pro-inflammatory cytokine interferon-γ contribute to hair follicle stem cell loss in lichen planopilaris.

The researchers reported that basal cell carcinoma tumor cells strongly express keratins typical of basal keratinocytes and some hair follicle components but lack differentiation markers, suggesting a follicular or pluripotent stem cell origin.

This review discusses the evolving understanding of epithelial stem cells, noting how new models challenge old assumptions and suggesting multiple stem cell populations contribute differently to skin and hair follicle regeneration.

This review examines current knowledge on human epithelial hair follicle stem cells, their markers, and outlines challenges in translating findings from murine studies to human research, but does not report new experimental results.

In this study, miR-324-3p was found to promote differentiation and migration in cultured keratinocytes and is highlighted as a potential target for treating androgenic alopecia.

This study established a new cell line from human hair follicle stem cells that maintains stem cell properties and differentiation capabilities, providing a useful in vitro model for stem cell research.

This study found that activating CB1 receptor signaling in human hair follicles increased stem cell proliferation while reducing differentiated cell survival, suggesting CB1's role as a survival stimulus for epithelial stem cells.
