Cell migration signaling pathways

“Cell migration signaling pathways” refers to a diverse class of intracellular signal transduction cascades that control the movement of cells in response to external stimuli and internal cues. These pathways coordinate actin cytoskeleton remodeling, assembly and disassembly of focal adhesions, and polarity changes required for directional movement. Key molecular players include small GTPases (RhoA, Rac1, Cdc42), PI3K/Akt, MAPK/ERK, JNK, integrins, focal adhesion components, and downstream transcription factors. These signaling networks are fundamental to physiological processes such as embryonic development, tissue repair, and immune surveillance, but aberrant activation or dysregulation contributes to disease states including cancer metastasis, chronic inflammation, and fibrosis. Targeting these pathways for therapy requires precise intervention, as they are essential for basic cellular homeostasis across many cell types.
