Figure 4From: Responsiveness of bovine cumulus-oocyte-complexes (COC) to porcine and recombinant human FSH, and the effect of COC quality on gonadotropin receptor and Cx43 marker gene mRNAs during maturation in vitroFigure 4A. Expression of LHr mRNA in three COC quality grades at 6, 12, 18 and 24 h of maturation. Mean ± standard error (n = 4 replicates). abCOC quality grades with no superscripts in common are different, at least P < 0.05. Figure 4B. Expression of LHr mRNA in three quality grades of COCs washed in heparin-free media at 0 h and 6 h of maturation. Mean ± standard error (n = 4 replicates).Back to article page
