Paracrine signaling pathway involved in tissue regeneration

Paracrine signaling pathways involved in tissue regeneration encompass the local release of signaling molecules (growth factors, cytokines, chemokines, microRNAs in exosomes) by cells at an injury site. These pathways mediate cell proliferation, differentiation, survival, tissue patterning, stem cell activation, and immune modulation—chiefly through binding to specific receptors on neighboring cells and activating cascades like receptor tyrosine kinase or TGF-β signaling. They are essential for wound healing, organ regeneration, and responses to injury; dysregulation is implicated in diseases including cancer and fibrosis. Advances in regenerative medicine and stem cell therapies increasingly rely on manipulating paracrine signaling rather than direct cell replacement.

Drugs may act by: Inhibiting or stimulating growth factor receptors (e.g., FGFR inhibitors); Modulating cytokine release or action; Blocking or enhancing signaling cascades (e.g., MAPK, PI3K); Promoting or suppressing paracrine factor production (e.g., stem cell therapy latest approaches)
