January 2019 in “Animals” The study examined the role of Platelet-Derived Growth Factor A (PDGFA) in the hair follicle cycle of cashmere goats, using 7 one-year-old female goats. It found that PDGFA, along with Bone Morphogenetic Protein 2 (BMP2), had higher expression levels during the late catagen and early anagen phases, indicating their involvement in hair follicle growth and activation of hair follicle stem cells. PDGFA was localized in the basal layer of the outer root sheath and showed stronger immunostaining in regressive hair follicles. The research suggested that PDGFA played a significant role in promoting hair growth and could aid in improving cashmere fiber production.
