초록

본 실험은 원시난포의 체외배양 체계를 확립할 수 있는 가능성을 검토하기 위해 0, 5, 10, 15 및 20일령 마우스에서 분리한 난소를 20, 15, 10, 5 및 0일동안 organ culture 하여 난소의 성장률, 난자의 회수율과 성장률 및 난자의 핵성숙 단계를 조사하여, 비교 ·검토하였다. 그 결과를 요약하면 다음과 같다. 1. Organ culture 전과 후의 각 일령에 따른 난소의 면적 차이는 0일령 35.9%, 5일령 8.7%, 10 일령 1.2% 및 15일령 14.4%로 15일령을 제외 하고는 배양일령이 증가할수록 면적 차이는 감소하였다. 2. Organ culture 후 난자의 회수율과 난자의 직경은 배양일령이 증가할수록 증대되었다. 3. GV기 이상의 핵성숙은 organ culture 후 배양 일령이 증가할수록 진행되는 단계에 있는 것으로 나타났다.

This study was to assess the developmental capacity of oocytes matured in vitro after 20, 15, 10, 5 and 0 days of organ culture when ovaries were isolated from juvenile mice at 0-, 5-, 10-,15- and 20-day old, respectively, and to develop in vitro culture system that observed a view to morphology of ovaries and nucleus maturation of oocytes. The size of ovaries decreased 35.9%, 8.7%, 1.2% and 14.4% after 20, 15, 10, 5 days of organ culture when the ovaries were isolated from 0-, 5-, 10 and 15-day old mice, respectively. After organ culture, the recovery rates, diameters of oocytes and the number of oocytes progressed from GV to MII were increased as increasing age of mice.
