Review Paper: Application of Hair Follicle Bulge Stem Cells in Wound Healing
Authors
Abstract:
Despite the significant advances in regenerative medicine, wound healing has remained a challenging clinical problem. Skin is the largest human organ with many vital functions; therefore, any damage to its normal structure should be treated as soon as possible. Easy access to skin stem cells has created a lot of excitement in therapeutic applications. “Cell therapy” is considered a novel method in regenerative medicine, especially when conventional treatments fail. Candidate cell populations for therapeutic applications include embryonic, induced pluripotent, adult mesenchymal, and hair follicle stem cells. It is possible to differentiate stem cells separated from the bulge area of hair follicle into neurons, melanocytes, keratinocytes, glia and smooth muscle cells that are negative for the keratinocyte marker kr15. This review discusses the plasticity of skin stem cells, especially stem cells located in the hair follicle and their involvement in wound healing, gene expression profile in wound healing, hair follicle stem cells, and their surrounding epidermis. Moreover, the ability of hair follicle stem cells for treating wounds and regenerative medicine is going to be discussed. Eventually we suggest the hair follicle as an ideal source of stem cells for cell therapy and regenerative medicine because they are abundant with easy access and great differentiation ability.

Effects of Hair Follicle Stem Cells on Partial-Thickness Burn Wound Healing and Tensile Strength
Background: The recent improvements in wound healing have led to new strategies in regenerative medicine. Burn wound healing is an important issue in skin regeneration and has multiple indications for stem cell therapy. Hair follicle stem cells (HFSCs) are a highly promising source of stem cells for healing use, as these cells are accessible, active and pluripotent adult stem cells. Methods: HF...

The cutaneous healing response has evolved to occur rapidly, in order to minimize infection and to re-establish epithelial homeostasis. Rapid healing is achieved through complex coordination of multiple cell types, which importantly includes specific cell populations within the hair follicle (HF). Under physiological conditions, the epithelial compartments of HF and interfollicular epidermis re...
full textBulge Region as a Putative Hair Follicle Stem Cells Niche: A Brief Review
BACKGROUND Hair follicle stem cells exist in different sites. Most of the hair follicle stem cells are reside in niche called bulge. Bulge region is located between the opening of sebaceous gland and the attachment site of the arrector pili muscle. METHODS Data were collected using databases and resources of PubMed, Web of Science, Science Direct, Scopus, MEDLINE and their references from the...

Notch signaling plays an important role in hair follicle maintenance, and it has been suggested that Notch is also required for follicular fate selection by adult hair follicle stem cells in the bulge. Here we demonstrate that, on the contrary, Notch signaling in bi-potential bulge stem cells or their uncommitted descendents acts to suppress the epidermal fate choice, thus ensuring follicular f...
