细胞凋亡是指生物体内细胞在特定的内源和外源信号诱导下,其死亡途径被激活,并在有关基因的调控下发生的程序性死亡过程。作为程序性细胞死亡的一种主要形式,细胞凋亡是多细胞生物体的重要的自稳机制之一,它的异常在肿瘤的发病上具有重要作用。凋亡是细胞死亡的高度保守形式,在多种组织中对于控制细胞的数量起到关键性的作 Apoptosis refers to the process of programmed death in a living body whose cells are activated under the guidance of specific endogenous and exogenous signals and under the control of relevant genes. As a major form of programmed cell death, apoptosis is one of the most important self-stabilizing mechanisms of multicellular organisms. Its abnormality plays an important role in the pathogenesis of tumors. Apoptosis is a highly conserved form of cell death that plays a key role in controlling the number of cells in many tissues
