Anti-apoptotic Bcl-2 protein function is required to maintain a hair follicle subpopulation of stem cells in murine skin. Blocking cell death by Bcl-2 overexpression affects the hair follicle stem cell niche and hair follicle regeneration. Systemic blocking of Bcl-2 specifically depletes supra-basal hair follicle stem cells. WebThey are located at the upper bulge, bulge, and secondary hair germ regions, though they can be replenished by neighboring cells when injured. To initiate hair regeneration, hair germ cells first proliferate and generate the differentiating lineages in response to DP signaling, followed by bulge stem cell activation. the mermaid 2016 sub indo
