肝细胞凋亡

细胞凋亡是一种程序性细胞死亡，属于单个细胞死亡，而不是局部大量细胞同时死亡。图为病毒性肝炎时肝细胞调亡，箭头所指凋亡细胞。凋亡细胞体积增大，胞质呈粉红色，肥质微细结构消失，无细胞核。细胞核和细胞质由于酶的作用变成了碎片。

Apoptosis is a more orderly process of cell death. Apoptosis is individual cell necrosis, not simultaneous localized necrosis of large numbers of cells. In this example, hepatocytes are dying individually (arrows) from injury through infection by viral hepatitis. The apoptotic cells are enlarged, pink from loss of cytoplasmic detail, and without nuclei. The cell nucleus and cytoplasm become fragmented as enzymes such as caspases destroy cellular components.
