mechanical compression

Mechanical compression refers to the physical application of pressure to cells or tissues, resulting in changes in cell shape, tension, and biochemical signaling. In biological systems, mechanical compression influences cell fate decisions, quiescence, activation, and migration. It acts via mechanosensitive proteins—including Piezo ion channels, integrins, and the YAP/TAZ pathway—to transduce physical forces into biochemical signals. This process is fundamental in diverse physiological contexts such as organ development, stem cell niche maintenance, injury repair, and coordinated migration. In disease, abnormal compression and mechanotransduction contribute to tumor invasion, tissue fibrosis, and compromised regeneration. Therapies do not directly target "mechanical compression," but rather the molecular machinery responsive to force[1][2][4][5][7][9].

mechanical compression triggers cell signaling by activating mechanosensitive proteins such as Piezo1 ion channels, integrins, YAP/TAZ, and TRPV4, which then induce intracellular signaling cascades
