Abstract: This experiment was conducted to study the effect of follistatin (FST) on the proliferation of goat ovarian follicular granulosa cells. Primary ovarian follicular granulosa cells were isolated and cultured from goat ovarian tissue. The goat FST was cloned by RT-PCR, shRNA fragment was designed, and lentiviral overexpression vector and interference vector were constructed. The effect of overexpression and interference were detected by qPCR technique, and the proliferation effect of the cells was detected by CCK-8 assay. Goat ovarian follicular granulosa cells were identified by immunofluorescence of follicle stimulating hormone receptor (FSHR), and the positive rate was 95%. After the lentivirus infected granulosa cells, the expression of fluorescent protein accounted for 80%. The effect of overexpression of FST and interference with lentiviral vector were both significant (P<0.05) by qPCR. Overexpression of FST significantly (P<0.05) inhibited the proliferation of granulosa cells, and interfered with FST significantly (P<0.05) promoted granulosa cell proliferation. The ovarian follicular granulosa cells were isolated; the FST overexpression and interference vectors were successfully constructed. The infection results indicated that FST could inhibit the proliferation of goat ovarian follicular granulosa cells. It provides basic data for further study of the role of FST in the regulation of mammalian follicular development and its mechanism.
