Figure 3From: Cyclic guanosine monophosphate does not inhibit gonadotropin-induced activation of mitogen-activated protein kinase 3/1 in pig cumulus-oocyte complexes Effect of cGMP analogues on cGMP concentration in cultured COCs. (a) COCs were cultured in medium supplemented with various concentrations of 8-Br-cGMP or (b) 8-CPT-cGMP for 4 h. The different superscripts above the columns indicate significant differences (P < 0.05).Back to article page
