PDGF-AA

PDGF-AA (Platelet-Derived Growth Factor-AA) is a protein that plays a key role in cell growth, division, and healing, particularly in tissues like skin and blood vessels. It is released by platelets during injury to stimulate the repair process, encouraging the growth of new cells and blood vessels. PDGF-AA specifically targets certain cells such as fibroblasts, which are essential for tissue repair and maintaining connective tissue strength. Overall, it’s a natural signaling molecule that helps coordinate tissue regeneration and healing after injury.
