给未成熟的大鼠服用PMSG,然后给予排卵剂量的hCG。成熟周期大鼠在间情期给予一定剂量的hCG,在内源性黄体生成素高峰出现前24小时给药。取单个卵泡的颗粒细胞,在激素作用后不同时间进行流式细胞仪检测。给未成熟大鼠服用PMSG后,颗粒细胞(处于细胞周期的S、G2或M期细胞)显著、短暂地增加。给成年周期大鼠注射hCG后,颗粒细胞的“周期”增加很少,但很明显。这些结果表明,hCG诱导的黄体生成实际上并不伴随着细胞增殖的停止。然而,这些数据为自己提供了另一种解释。观察到的相移可能是由于S和G2期持续时间的延长,表明细胞增殖率实际下降。流式细胞术被发现是研究大鼠卵泡生长的一种快速、廉价的工具,但由于卵泡之间的差异以及需要2000个细胞的最小样本大小,它的应用仅限于大卵泡。
Immature rats were given PMSG followed by an ovulatory dose of hCG. Mature cyclic rats were given an ovulatory dose of hCG on the day of dioestrus, 24 h before the endogenous LH surge was expected to occur. Granulosa cells from individual follicles were subjected to flow cytometry at various times after hormone administration. Administration of PMSG to immature rats caused a marked, transient increase in 'cycling' granulosa cells (cells in S, G2, or M phases of the cell cycle). Administration of hCG to adult cyclic rats caused a slight, but significant, increase in 'cycling' granulosa cells. The results could be taken to indicate that hCG-induced luteinization is not, in fact, accompanied by cessation of cellular proliferation. However, the data lend themselves to alternative explanations. The observed phase shifts may be due to the lengthening of the duration of S and G2 phases, indicating an actual decrease in the rate of cell proliferation. Flow cytometry was found to be a rapid, inexpensive tool for the study of follicular growth in the rat, but, due to variation between follicles and the need for a minimal sample size of 2000 cells, its application is limited to large follicles.
