Summary The precise localization of estrogen biosynthesis in the ovary of rats and mice were immunocytochemically studied using new antisera against aromatase cytochrome P-450. The positive reaction for aromatase was detected mainly on the granulosa cells of large, apparently preovulatory follicles. In addition, the cells of some corpora lutea showed very weak positive reaction but most corpora lutea were negative to the staining. Those cells such as the granulosa cells of smaller follicles, the theca interna cells, the interstitial gland cells, oocytes, peritoneal epithelial cells were entirely negative. These results indicate that in the ovary of rats and mice, the granulosa cells of preovulatory follicles are the main site for synthesis of estrogen from androgen which is provided by the theca interna cell and the interstitial gland cell.
