人卵泡液中含有胰岛素样生长因子I(IGF-I)及其低分子量结合蛋白(IGF-BP)。我们研究了体外受精中超排卵后获得的颗粒细胞合成IGF-BP的情况。将颗粒细胞在补充有10%胎牛血清(FCS)的Ham’s F-10培养基中培养72小时。每24小时收集培养基样品。培养基中的IGF-BP浓度在48 h时从1.2 μ g/l增加至2.1 μ g/l,在72 h时增加至3.3 μ g/l。通过SDS聚丙烯酰胺电泳(PAGE)和荧光法检测,标记的甲硫氨酸掺入免疫反应性IGF-BP中,显示IGF-BP的从头合成。我们的研究结果表明IGF-BP的合成在人类卵巢。
Human follicular fluid contains insulin-like growth factor I (IGF-I) and its low molecular weight binding protein (IGF-BP). We studied the synthesis of IGF-BP by the granulosa cells obtained after ovarian hyperstimulation for in vitro fertilization. The granulosa cells were cultured for 72 hours in Ham's F-10 medium supplemented with 10% fetal calf serum (FCS). Samples of the culture medium were collected every 24 hours. The IGF-BP concentration in culture medium increased from 1.2 to 2.1 micrograms/l at 48 h and to 3.3 micrograms/l at 72 h. De novo synthesis of IGF-BP was shown by incorporation of labeled methionine into immunoreactive IGF-BP, as detected by SDS polyacrylamide electrophoresis (PAGE) and fluorography. Our results demonstrate synthesis of IGF-BP in the human ovary.
