Effect of CNP on spontaneous and FSH-induced maturation of pig cumulus-enclosed oocytes. (a) Effect of CNP (100 nM) on spontaneous maturation of oocytes. (b) Effect of CNP on maturation of oocytes induced by FSH (1 IU/ml). GV, germinal vesicle; GVBD, germinal vesicle breakdown; MII, metaphase II. Significant differences were only found between FSH and FSH + CNP groups after 24 h of culture. Approximately 75 COCs were included in each group.
