본 연구에서는 clonal cell lines을 효율적으로 확립할 수 있는 방법을 제시하기 위하여 배양액 내에 catalase와 ME 첨가가 clonal cell line 확립 효율에 미치는 영향을 검토하였다. 임신 50일령의 암퇘지에서 얻은 태아섬유아세포를 2회 passage한 후 동결 보관하였다가 실험에 이용하였다. 단일세포를 catalase나 ME가 첨가된 배양액이 들어 있는 96-well dish로 옮겨 배양하였다. 단층이 형성된 세포는 4-we
This study was performed to examine the effects of catalase and -mercaptoethanol (ME) on the establishment of clonal lines from porcine fetal fibroblast cells. Fibroblasts derived from a pig fetus (Day 50) were passaged two times before use. A single cell was seeded in 96-well plates and cultured in medium supplemented with or without catalase or ME. Cell colonies were passaged two times into 4-well dish. Cell lines with proliferating potential were classified as an established clonal cell line. In experience 1, the establishment efficiencies were examined by addition of catalase (100ng/) or ME (100 uM) in culture medium. The establishment efficiency of ME-added group (8.3％) was significantly higher than that of control group (3.2％, P<0.05). However, catalase did not have a positive efffct on the establishment efficiency. In experience 2, the establishment efficiencies were examined by addition of different concentrations of catalase (0-1,000 ng/) in culture medium. However, establishment efficiencies were not different among the different concentrations of catalase (0-2.6％). In experience 3. the establishment efficiencies were examined by addition of different concentrations of ME(0-1,000 uM) in culture medium. The establishment efficiency was significantly higher in 100 uM ME-added group (9.4％) compare to others (0-1.6％). The result of present study shows that the establishment efficiency of clonal cell lines can be enhanced by the culture in media supplemented with 100uM ME. However, catalase did not have a positive effect on the establishment efficiency.
