초록

This study was performed to evaluate the effects of fibroblast co-culture on in vitro maturation (IVM) of prepubertal mouse preantral follicles. The intact preantral follicles were obtained from the ovaries of 12-14 day old mice and these were cultured individually in ${\alpha}$-minimal essential medium (${\alpha}$-MEM) supplemented with 5% fetal bovine serum (FBS), $100mIU/m{\ell}$ recombinant follicle stimulating hormone (rFSH), 1% insulin-transferrin-selenium, $100{\mu}g/ml$ penicillin and $50{\mu}g/m{\ell}$ streptomycin as base medium for 12 days. A total of 200 follicles were cultured in base medium co-cultured with mouse embryonic fibroblast (MEF) (MEF group) (n=100) or only base medium as control group (n=100). Survival rate of follicles on day 12 of culture were significantly higher in the MEF group of 90.0%, compared with 77.0% of the control group (p=0.021). Follicle diameters on day 6 and 8 of the culture period were significantly larger in the MEF group than those in the control group (p=0.021, p=0.007, respectively). Estradiol levels in culture media on day 4, 6, 8, 10 and 12 of the culture period were significantly higher in the MEF group (p=0.043, p=0.021, p=0.006, p<0.001 and p=0.008, retrospectively). Our data suggest that MEF cell co-culture on IVM of mouse preantral follicle increases survival rate and promotes follicular growth and steroid production.
