protein that inhibits activins, influencing muscle growth and hair
Follistatin, also known as FS or FST, is a protein that plays a crucial role in regulating various biological processes by binding to and inhibiting members of the TGF-beta superfamily, particularly activins. This inhibition is important for controlling muscle growth, inflammation, and tissue repair. In the context of hair biology, follistatin has been studied for its potential to promote hair growth and counteract conditions like alopecia by modulating the activity of growth factors involved in hair follicle development.
