Abstract: | We have established transgenic mice expressing the Cre recombinase under the control of the anti-Müllerian hormone (AMH) gene promoter. Cre activity and specificity were evaluated by different means. In AMH-Cre mice, expression of the Cre recombinase mRNA was confined to the testis and ovary. AMH-Cre mice were crossed with reporter transgenic lines and the offspring exhibited Cre-mediated recombination only in the testis and the ovary. In male, histochemical analysis indicated that recombination occurred in every Sertoli cells. In female, Cre-mediated recombination was restricted to granulosa cells, but the protein was not evenly active in every cells. From these results, we conclude that potentially, this transgenic line possessing AMH promoter-driven expression of the Cre recombinase is a powerful tool to delete genes in Sertoli cells only, in order to study Sertoli cell gene function during mammalian spermatogenesis. |
