The present study was conducted to gain insights into oocyte maturation and early embryo development, SELDI-TOF-MS was used to find the protein candidates that are specifically or prominently expressed in mouse oocytes at the in vitro matured metaphase II (MIl) and germinal vesicle (GV) stages. By using selected CM10 chip, found 16 candidates which were up-regulated in GV stage oocytes compared with in MIl stage oocytes, molecular weight are 8180 (2 candidates), 10226 (5 candidates), 15767 (5 candidates) and 16770 (4 candidates) Da respectively. And 29 candidates were higher in MIl than in GV stage oocytes, molecular weight are 10832 (3 candidates), 17744(8 candidates), 20122 (3 candidates), 22131 (3 candidates), 24857 (7 candidates) and 33507 (5 candidates) Da, respectively. All (45) candidate (0.2 and 1.0 % error tolerances) were performed real time RT-PCR analysis and further selected 13 more potential candidates.

본 연구는 발정주기에 따른 개의 미성숙난자의 체외배양 0시간째 핵의 발달단계를 비교ㆍ검토하였다. 발정주기가 다른 개의 난소를 적출 하여 항생제가 첨가된 38℃의 0.9% 생리식염수가 들어있는 보온병에 넣어 2시간 이내에 연구실로 운반하고 난소를 면도날로 세절하여 난포란을 회수하였고, 난구세포 제거 후 Chohan과 Hunter (2003) 방법에 준하여 10 ug/ml Hoechst 33342를 이용한 핵염색을 실시하여 핵의 모양을 판명하였다. 조사된 결과는 SAS 8.0 Package를 이용하여 통계분석을 실시하였다. (중략)

많은 연구에서 돼지의 난포란 혹은 배아가 낮은 온도에 대해 민감한 것은 세포질 내에 함유된 지방구와 관련이 있다고 하였으며, 이런 세포질내의 지방구를 제거함으로 동결능력이 향상된다고 하였다. 이렇게 지방구가 제거된 돼지의 난포란과 배아를 효과적으로 동결보존하기 위해서는 새로운 개념의 동결보존 기술이 필요하다고 하겠다. 따라서, 본 연구는 미성숙 단계에서 지방이 제거된 돼지 난포란의 유리화 동결에 적합한 방법을 찾기 위하여 straw를 이용한 유리화 동결법과 electron microscopic grid(EM grid)를 사용한 유리화 동결법을 실시하여 효율적인 동결방법을 검토하였다.
