英文摘要
In humans, age-related increase of aneuploidy in oocytes is known as one of the causes of the birth of offspring with Down's syndrome or miscarriage. It has been suggested that the decrease of the molecules, cohesins, involving chromosome segregation in meiosis contributes aneuploidy. In this study, I asked whether the amount of cohesins has actually decreased in aged human oocytes, and showed that the cohesins of oocytes could be detected in aged women. However, the comparison between ages has not yet proceeded because of the unavailability of enough samples at this time.
