FGF5 (Fibroblast Growth Factor 5): FGF5 is a member of the fibroblast growth factor family, a group of proteins known for their roles in cellular proliferation, differentiation, and signaling. As a key mediator of biological processes, FGF5 is involved in the regulation of hair growth cycles, and its activity has been linked to influencing hair length in various species. Beyond its role in hair follicle regulation, FGF5 contributes to the development and repair of tissues, including the nervous system, where it plays a role in neural development. Dysregulation of FGF5 has been implicated in certain pathological conditions, such as cancer,...
