细胞是组成生物体的基本单位。在多细胞生物体中 ,细胞的增殖和死亡之间的平衡是维持体内平衡的重要方式 ,使得细胞数目得以控制。如果细胞增殖和死亡之间失去平衡 ,则会伴随疾病的发生 ,如癌症、自身免疫性疾病等细胞增生性疾病及艾滋病、神经变质性疾病、缺血性疾病和包括心 Cells are the basic units that make up an organism. In multicellular organisms, the balance between cell proliferation and death is an important way to maintain homeostasis so that the number of cells can be controlled. If there is a loss of balance between cell proliferation and death, it will be accompanied by the onset of diseases such as cell proliferative diseases such as cancer and autoimmune diseases and AIDS, neurodegenerative diseases, ischemic diseases and diseases including heart
