Cell migration promotion

Cell migration promotion" refers to the ensemble of molecular and cellular processes that enhance or enable the movement of cells, usually in response to extracellular cues. This is not a single molecule or receptor but encompasses coordinated activity of cell surface receptors, intracellular signaling molecules (such as Rho-family GTPases), cytoskeletal elements (actin filaments, myosin II), adhesion complexes (integrins, FAK, paxillin), and extracellular signals (chemokines, growth factors, cytokines)[1][3][5]. Promoting cell migration underlies processes such as embryonic development, wound healing, immune responses, and is co-opted during cancer metastasis. Key molecular pathways involved include those regulated by Rho/Rac/Cdc42 GTPases, PI3K, TORC2, integrin signaling, and pathways driving epithelial–mesenchymal transition (EMT)[1][3][6]. Because it is a process rather than a discrete molecule, it cannot be directly targeted, but interventions may influence specific components or regulators of migration.
