Expression of NPR2 and NPPC in COCs cultured in vitro in FSH-supplemented medium. The relative abundance of specific gene mRNA was assessed in COCs cultured with FSH (1 IU/ml) for the indicated periods of time by a real-time RT-PCR and is expressed in arbitrary units as fold increases in the specific gene/ACTB ratio over the level found in control COCs at time 0 h. The different superscripts above the columns indicate significant differences (P < 0.05).
