Table 1.
Granulosa and theca cells were isolated from preovulatory follicles 36 h after a luteolytic dose of PGF2α and cultured for 12, 24, 36, and 48 h. “+”, results indicate that the hormone (P4 or PG) has a positive effect on levels of the mRNA, mimicking the effects of gonadotropins; “−”, results indicate an effect that did not mimic that of the gonadotropin; NC, results show no effect.
Granulosa or theca cells were cultured with LH (100 ng/ml), LH + mifepristone (PGR inhibitor), or LH + mifepristone + MPA (synthetic progestin).
Granulosa cells were cultured with LH (100 ng/ml) + graded doses of the COX-2 inhibitor NS398 (0.01, 0.1, and 1 μM).
Theca cells were cultured with PGE2 or PGF2α (1 μM).
