Hair Follicle Stem Cells: An Overview And Therapeutic Applications

Stem cells are characterized by their capacity for self-renewal and differentiation. This makes them essential components of tissue regeneration. Among adult populations, multipotent hair follicle stem cells (HFSCs), which are located primarily in the follicular bulge, show significant regenerative potential. This is due to their ability to differentiate into multiple lineages. This review examines HFSC biology and evaluates their therapeutic potential in wound healing, neural repair, and cardiovascular tissue engineering. Clinical applications of HFSC based therapies show evidence of success in treating androgenetic alopecia and chronic ulcers. While applications in neuroregeneration and vascular engineering remain mainly within the preclinical and in vitro stages. This article reviews recent advances in follicular compartmentalization and the discovery of actively dividing subpopulations. While also addressing the technical limitations and evidentiary gaps that must be solved before these therapies can transition into clinical practice.
