Autophagy generally exists in eukaryotic cells. It happens in normal cells through physical or pathological process in cell cycles.

Methods We measured the astrocyte cell cycles in different time after ischemia and anoxia by flow cytometry and detected the levels of GFAP and PCNA with fluorescence immunocytochemistry.

方法用流式细胞仪检测缺血缺氧后不同时间点星形胶质细胞细胞周期变化，并用荧光免疫细胞化学技术测定胶质细胞纤维酸性蛋白（GFAP）和增殖细胞核抗原（PCNA ）的表达水平。

They ran the cell through repeated cycles of assembly and disassembly over a 14-hour period, with no loss of efficiency.

在一个14小时的周期里他们让此细胞重复分解和合成的的循环，没有效率下降的情况。
