GlossaryPlatelet-Derived Growth Factor BB (PDGF-BB)

protein that stimulates cell growth and tissue repair

Platelet-Derived Growth Factor BB (PDGF-BB) is a protein that plays a crucial role in cell growth, healing, and the formation of blood vessels. It is one of the isoforms of PDGF and is particularly important in wound healing and tissue repair, as it stimulates the proliferation and migration of cells such as fibroblasts and smooth muscle cells.

community Surprisingly thorough study on He-Shou-Wu/Fo Ti

in Research/Science 14 upvotes 1 year ago

He Shou Wu (Fo Ti) extract was found to prolong the hair growth phase, inhibit 5-alpha-reductase (like finasteride), reduce androgen receptors, and increase growth factors, potentially outperforming minoxidil in recovering hair follicle size after DHT exposure. Two compounds, emodin and TSG, are identified as responsible for these effects and warrant further investigation.
