在哺乳动物中,细胞死亡主要包含两种不同的形式,一种形式是细胞在生理过程中意外死亡,称为细胞坏死,其作为一种被动性死亡的过程,常见于在不利因素下,细胞的正常代谢活动受损或中断,最终导致细胞受到不同程度的损伤。另一种死亡方式为细胞凋亡,是在基因控制下细胞主动性死亡的过程。就哺乳动物雌性生殖系而言,卵丘细胞通过缝隙连接与卵母细胞形成结构和功能上的一个合胞体,为卵母细胞提供大量的能量及营养物质。卵泡内微环境的变 In mammals, cell death consists mainly of two different forms, one in which the cell dies unexpectedly during a physiological process called cell necrosis as a passive process of death that occurs frequently under adverse conditions and that cells Of normal metabolic activity is damaged or interrupted, eventually leading to different degrees of cell damage. Another way of death is apoptosis, which is the process of cell death under the control of genes. In the mammalian female reproductive system, the cumulus cells form a syncytial structure and function with the oocyte through the gap, providing a large amount of energy and nutrients for the oocyte.
