Necrosis refers to irreversible cell damage and subsequent cell death resulting from pathogenic processes. It is an uncontrolled cell death that leads to enlargement of the cell organelles, plasma membrane rupture and final lysis of the cell, and intracellular contents leaking into the surrounding tissue, resulting in tissue injury. Unlike programmed cell death known as … Read more
