Programmed cell death (PCD) is a key phenomenon in regulating cell-numbers. Apoptosis is essentially required for a balanced homeostasis between cell proliferation and cell death in multicellular organisms. Apoptosis is especially relevant in the gastrointestinal tract, as the mammalian intestinal mucosa undergoes continual epithelia cell turnover.
程序性细胞死亡（PCD）是调节细胞数量的关键现象。细胞凋亡对于多细胞生物中细胞增殖与细胞死亡之间的平衡稳态至关重要。细胞凋亡在胃肠道中尤为重要，因为哺乳动物的肠黏膜上皮细胞会持续更新。
