细胞凋亡在哺乳动物细胞的发育、成长及疾病过程中都具有重要意义。为当前广大分子生物学家及医学家研究的热门课题。最近对细胞凋亡的概念有一些重要的改变；过去探索凋亡的机理常常以“细胞核”为中心，近年来发现“线粒体”才是细胞凋亡的枢纽部位［１］。过去对细胞凋亡多? Apoptosis plays an important role in the development, growth and disease of mammalian cells. For the current majority of molecular biologists and medical research hot topics. Recently, there have been some important changes in the concept of apoptosis. In the past, the mechanism of apoptosis was often centered on the “nucleus.” In recent years, “mitochondria” have been the focus of apoptosis [1]. Apoptosis in the past and more?
