The effects of NPs on the developmental competence of immature porcine oocytes from 4.1-6.0 mm follicles (mean ± S. E. M.)

	oocytes(n)	cleaved oocytes (%)	blastocysts (%)
control	214	40.5 ± 1.42 a	13.5 ± 2.9 a
cilostamide	267	47.2 ± 2.04 ab	15.2 ± 1.5 ab
BNP	245	52.1 ± 2.01 b	16.5 ± 2.6 b
CNP	223	51.9 ± 1.28 b	17.6 ± 2.3 b

Cleavage rates on day 2 and Blastocyst developmental rates on day 7 after IVF of the COCs recovered from the 4.1 - 6.0 mm follicles in standard IVM for 46 h (as negative controls), or pre-cultured with PMCI–cilostamide 20 h plus IVM 46 h (as positive controls) and pre-cultured with PMCI–BNP/CNP 20 h plus IVM 46 h (as experimental groups). ^abMeans in the same column with different superscripts were significantly different (p < 0.05)
