- 論文の詳細を見る
The regional differences in morphology and steroid production of granulosa cells of the animal and vegetal hemispheres of the preovulatory medaka (Oryzias latipes) follicles were investigated. Granulosa cells in the animal pole region were distinguishable from those in the vegetal pole region in their shape and distribution. The distribution of tall granulosa cells was more compact in the vegetal pole area than in the remaining areas. The gonadotropin-induced production of 17α, 20β-dihydroxy-4-pregnen-3-one by granulosa cells alone was at a level sufficient to induce in vitro maturation of the oocyte. Production was significantly greater in the vegetal hemisphere than in the animal hemisphere. These results indicate that medaka follicles have morphological and physiological differences in granulosa cells corresponding to regional differences along the animal-vegetal axis of the oocyte.
