Growth factor secretion-mediated tissue regeneration

Growth factor secretion-mediated tissue regeneration is a physiological process rather than a discrete molecular target. It involves the release of various signaling proteins—such as vascular endothelial growth factor (VEGF), fibroblast growth factor (FGF), and transforming growth factor-beta (TGF-beta)—which act in a paracrine or autocrine fashion to orchestrate tissue repair (Gnecchi et al., 2016, PubMed). This mechanism is the primary driver behind the therapeutic efficacy of mesenchymal stem cell (MSC) therapies and platelet-rich plasma (PRP), where the "secretome" stimulates endogenous cells to proliferate, migrate, and differentiate (Park et al., 2019, PubMed). While clinically significant for treating chronic wounds and degenerative diseases, it represents a complex biological pathway involving multiple receptors and ligands rather than a single druggable protein. Consequently, therapeutic strategies often focus on delivering these factors or modulating the cells that produce them to enhance the natural regenerative response.
