The hormone progesterone induces resumption of the meiotic cell cycle, leading to maturation of the oocyte into a fertilizable egg. We investigated the effect of hypergravity on Xenopus oocyte maturation. At the last meeting, we reported that hypergravity did not affect the initiation of maturation, whereas the progression of maturation was affected regarding the external appearance of the white spot. The present study examines changes in spindle morphology during Xenopus oocyte maturation. Cytological examination showed that spindle formation of meiosis II was largely inhibited, although meiosis I was successfully completed. These findings suggest that hypergravity inhibits the bipolar spindle formation of meiosis II, and hence adversely affects the process of oocyte maturation in Xenopus laevis.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号:
