Growth Factor Secretion

Meaning

Growth Factor Secretion is the process by which cells synthesize and release specific polypeptide molecules, known as growth factors, that regulate cell proliferation, differentiation, survival, and tissue repair. These secreted proteins act as potent local or systemic signaling molecules, influencing cellular activity in an autocrine, paracrine, or endocrine manner. Optimizing the secretion of factors like IGF-1 and various fibroblast growth factors is critical for maintaining tissue health, promoting regeneration, and supporting longevity.
