TLDR Epidermal stem cells help renew skin and regenerate hair follicles.
The document discussed the role of epidermal stem cells in maintaining skin homeostasis and hair follicle regeneration. It highlighted that adult skin constantly renews itself, with stem cells in the epidermis playing a crucial role in this process. The epidermis is composed of interfollicular epidermis, hair follicles, and sebaceous glands, each containing progenitor or multipotent cells that activate during injury or the hair growth cycle. The article summarized the understanding of these stem cells, including evidence of progenitor cells in the interfollicular epidermis, their self-renewal capabilities in vitro, and the characteristics and gene expression of hair follicle bulge stem cells.

October 2012 in “Seminars in Cell & Developmental Biology” Different types of stem cells in hair follicles play unique roles in wound healing and hair growth, with some stem cells not originating from existing hair follicles but from non-hair follicle cells. WNT signaling and the Lhx2 factor are key in creating new hair follicles.
