“…Nor are they seen in the com ponents of small follicles which are believed to form a part of ovarian strom a used in in vitro biochemical techniques [Savard et al, 1965;Rice and Savard, 1966|. However, the cvtological and histochemical features of steroid-producing cells are conspicuously developed in the theca interna cells of developing antral follicles in the hum an ovarv as well as in the ovaries of some other m am m alian species | G uraya, 1968k]. In the ovaries of some m am m alian species (flog, cattle and rhesus monkey) the epithelial cords also develop the histochemical features of steroid-producing cells [see Gi raya, 19681].…”
