Figure 5. Relative expression level obtained by qPCR of 9 genes differentially expressed according to oocyte developmental competence.

Results were expressed as means ± SEM of relative expression to the reference gene RPL19. CC_B+, cumulus cells from mature oocyte yielding a blastocyst at day 5/6 of in vitro culture once fertilised; CC_B-, cumulus cells from mature oocyte which stopped developing at the embryo stage at day 5/6 of in vitro culture once fertilised; *, significant difference (p<0.05).
