To evaluate the dose effect of recombinant mouse granulocyte-macrophage colony-stimulating factor (rmGM-CSF) or brain-derived neurotrophic factor (BDNF) in culture medium on the development of in vitro fertilized mouse embryos. Mature oocytes were retrieved from superovulated female BDF1 mice and inseminated by sperm from male BDF1 mice. On day 1, two-cell stage embryos were divided and cultured until day 5 in the embryo maintenance medium supplemented with 0, 1, 2, 5, or 10 ng/mL of rmGM-CSF or supplemented with 0, 5, 10, or 20 ng/mL of BDNF. Blastocyst formation rate and their cell numbers were assessed. The blastocyst formation rate and the total cell count in blastocyst was similar in all the rmGM-CSF treatment groups when compared with the control. However, the blastocyst formation rate and the total cell count was significantly higher in the group supplemented with 10 ng/mL of BDNF compared with the control (63.9%, 45.8±11.5 vs. 52.3%, 38.0±6.8; P<0.05, respectively). Supplementation of 10 ng/mL of BDNF enhanced the developmental potential of mouse preimplantation embryos, but supplementation of rmGM-CSF did not.
