Gosset Cellular Membrane Integrity Overview
Cellular membrane integrity refers to the structural and functional wholeness of the cell's plasma membrane. In cryodestruction, loss of membrane integrity is a primary mechanism leading to cell death. The membrane maintains cellular homeostasis, mediates signaling, and protects internal components. Disruption occurs through ice crystal formation, phase transitions in lipid bilayers, and dehydration injury. Factors like water permeability, lipid composition, and cryoprotectants influence susceptibility. Assessment involves fluorescent dyes and functional assays. While not a direct therapeutic target, maintaining or disrupting membrane integrity is critical in cryopreservation and cryodestruction, respectively.
