Effects of TNF during in vitro maturation on meiotic maturation and subsequent embryonic development of porcine oocytes following IVF/IVC^*.

TNF concentration	Percentage of oocytes reaching to MII (n)	Embryonic cleavage (n)	Blastocyst development (n)	Blastocyst/cleaved ^§	Blastocyst cell number (n)
0 ng/ml	66.1 ± 6.1% (62)	57.8 ± 2.9% (288)	23.0 ± 2.7% (288)	39.4 ± 4.0%	45.0 ± 2.3 (65)
0.1 ng/ml	62.5 ± 6.5% (58)	64.2 ± 3.0% (249)	25.8 ± 2.8% (249)	39.7 ± 3.9%	43.1 ± 2.8 (63)
1 ng/ml	50.0 ± 7.3% (48)	63.2 ± 2.7% (279)	26.1 ± 3.7% (279)	38.2 ± 4.8%	55.3 ± 2.8 (72)

Data are reported as mean ± SEM. No significant differences (P > 0.05) were found in percentage of oocytes reaching to MII and embryonic development in all treatment groups.

Percentage of blastocysts is calculated from the cleaved embryos.
