细胞凋亡 Apoptosis(重定向自Apoptotic)
![]() 细胞凋亡(英语:apoptosis,源自希腊语:απόπτωσις,有堕落,死亡之意),为一种细胞进程性死亡。相对于细胞坏死(necrosis),细胞凋亡是细胞主动实施的。细胞凋亡一般由生理或病理性因素引起。而细胞坏死则主要为缺氧造成,两者可以很容易通过观察区分开来。在细胞凋亡过程中,细胞缩小,DNA被核酸内切酶降解成180bp-200bp片段属于有层次之断裂,(可以通过凝胶电泳证明),而细胞坏死时,细胞肿胀,细胞膜被破坏,通透性改变。细胞器散落到细胞间质,需要巨噬细胞去清除,结果是该局部组织发炎。相比起细胞坏死,细胞凋亡是更常见的细胞死亡形式。

Apoptosis 细胞凋亡(重定向自Apoptotic)
![]() ![]() ![]() ![]() Apoptosis (from Ancient Greek ἀπόπτωσις "falling off") is a process of programmed cell death that occurs in multicellular organisms. Biochemical events lead to characteristic cell changes (morphology) and death. These changes include blebbing, cell shrinkage, nuclear fragmentation, chromatin condensation, chromosomal DNA fragmentation, and global mRNA decay. Between 50 and 70 billion cells die each day due to apoptosis in the average human adult. For an average child between the ages of 8 and 14, approximately 20 billion to 30 billion cells die a day. |
