Table 3 Fertilization and embryo development rates from bovine oocytes in vitro matured in TCM, SOF or SOF supplemented with 100 ng/ml of GM-CSF

From: Granulocyte-macrophage colony stimulating factor (GM-CSF) enhances cumulus cell expansion in bovine oocytes

Treatment Oocytes (n) Cleavage (%) Blastocysts day 7 (%) Blastocysts/ cleavage day 9 (%) Blastocyst/ oocytes day 9 (%) Embryonic nuclei (n)
TCM 216 146 (67.6)a 55 (37.7)a 60 (41.1)a 27.8a 108.2 ± 7.7
SOF 212 122 (57.5)b 35 (28.7)b 38 (31.1)b 17.9b 98 ± 12.6
SOF + GM-CSF (100 ng/ml) 224 113 (50.4)b 36 (31.9)b 39 (34.5)b 17.4b 96 ± 13.1
