| pubmed-article:3921769 | pubmed:abstractText | The effect of serum and 12-O-tetradecanoylphorbol-13-acetate (TPA) on the FSH-stimulated oestrogen production was studied in both cell and organ cultures. Ovaries were removed from (WB X C57BL/6)F1 mice at 9-days of age, and the conversion of 4-androstene-3,17 -dione to oestrogens was stimulated by the addition of FSH in vitro. Either 10% serum (fetal calf, mouse, rat and horse) or 0.1 microM TPA markedly inhibited the FSH-stimulated oestrogen production by dispersed and cultured ovarian cells. In contrast, neither serum nor TPA influenced the oestrogen production in the organ culture. This suggests that the presence of tissue architecture may prevent the inhibitory effect of serum and TPA on the FSH-stimulated oestrogen production. | lld:pubmed |
