细胞凋亡(apoptosis)是一种生理性、程序性的细胞死亡过程。通过凋亡,体内失去生物学活性或无生理功能的细胞,如一些衰老、受损或癌变前的细胞以有序的方式被清除,从而维持组织中细胞生成与细胞死亡之间的平衡。细胞凋亡是广泛存在于组织细胞中的正常现象,属于一种机体的自主保 Apoptosis (apoptosis) is a physiological, programmed cell death process. By apoptosis, cells that lose their biological activity or have no physiological function in vivo, such as some aging, damaged or pre-cancerous cells, are cleared in an orderly manner to maintain a balance between cell production and cell death in the tissue. Apoptosis is a normal phenomenon that exists in a wide range of tissue cells and belongs to an organism’s autonomous
