Table 7.
The effects of NPs on the developmental competence of immature porcine oocytes from 6.1-8.0 mm follicles (mean ± S. E. M.)
oocytes(n) | cleaved oocytes (%) | blastocysts (%) | |
---|---|---|---|
Control | 294 | 30.9 ± 1.1 a | 8.3 ± 1.7 a |
cilostamide | 263 | 23.2 ± 2.3 b | 4.7 ± 2.4 b |
BNP | 301 | 25.1 ± 1.6b | 5.1 ± 3.3 b |
CNP | 268 | 24.6 ± 1.0 b | 5.0 ± 1.8 b |
Cleavage rates on day 2 and Blastocyst developmental rates on day 7 after IVF of the COCs recovered from the 6.1 - 8.0 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)
