OBJECTIVE
To investigate the influence of granulocyte colony stimulating factor (G-CSF) and granulocyte macrophage colony stimulating factor (GM-CSF) on preimplantation development and implantation in mouse embryos. MATERIAL AND METHODS: Eight-cell stage mouse embryos were cultured for 96 hours with G-CSF or GM-CSF at concentrations of 10 pg/ml, 100 pg/ml, 1 ng/ml and 10 ng/ml. Embryos not treated with G-CSF or GM-CSF were served as control. The percentages of embryos which developed to expanded, hatched blastocyst stage and in vitro implantation at 96 hours were determined. Results were analyzed with Kolmogorov-Smirnov test and analysis of variance (ANOVA). The statistical significance was defined as p<0.05. RESULTS: The percentages of fully expanded blastocysts in all G-CSF and GM-CSF treatment groups were not significantly different from the control. The percentages of hatched blastocysts were significantly higher in 100 pg/ml and 10 ng/ml of G-CSF treatment group compared to the control (p<0.05, p<0.05, respectively). The percentages of hatched blastocysts were significantly lower in 1 ng/ml of GM-CSF treatment group compared to the control, 10 pg/ml, and 100 pg/ml of GM-CSF treatment group (p<0.05, p<0.05, p<0.05, respectively), and the percentages of hatched blastocysts were also significantly lower in 10 ng/ml of GM-CSF treatment group compared to the control and 100 pg/ml of GM-CSF treatment group (p<0.05, p<0.05, respectively). The percentages of implanted blastocysts in vitro were significantly higher following incubation with all concentrations of G-CSF compared to the control and, especially in 100 pg/ml and 10 ng/ml of G-CSF treatment groups compared to the control and other treatment groups. The percentages of implanted blastocysts in vitro were significantly higher in 10 pg/ml of GM-CSF treatment group than the control and 100 pg/ml of GM-CSF treatment groups (p<0.05, p<0.05, respectively). CONCLUSION: G-CSF and GM-CSF might influence on embryonic development and implantation in mouse embryos. |
