Physical external compression

Physical external compression refers to the application of a compressive mechanical force onto biological tissues or cells from an external source. In biological systems, such compression can affect cell shape, proliferation, differentiation, apoptosis, gene expression, cytoskeletal dynamics, and mechanotransduction pathways. These changes are mediated by mechanosensitive molecules and signaling pathways (such as integrins, stretch-activated ion channels, and the Rho GTPase family), but the compressive force itself is not a molecule or protein. Physical external compression is employed in clinical settings (e.g., to enhance blood or lymphatic flow), basic cell biology experiments, and is relevant in disease contexts such as cancer, wound healing, and edema. It can have both beneficial and deleterious biological consequences depending on magnitude, duration, and tissue type[1][2][3][4][5][6]. Physical external compression is not a canonical drug target, enzyme, transporter, or receptor, and instead represents a mode of mechanical stimulus with broad biological effects[2][3][4].
