Ultrastructural changes in differentiating micropylar cells and in the micropyle occur during oogenesis in the medaka, Oryzias latipes. A micropylar cell is not detectable in previtellogenic ovarian follicles. In the early vitellogenic phase, the micropylar cell becomes differentiated from neighboring granulosa cells by its electrondense cytoplasm. The… CONTINUE READING
