Effects of Placental Isoferritin on the Mouse Embryo Development in vitro

To investigate the effect of placental isoferritin (PLF) on mouse embryo development in vitro, mice 2-cell embryos were co-cultured with human first trimester decidual cells at different concentrations of PLF in vitro. The following changes of the above system were observed under an invert microscope and the number of embryos were recorded and the embryos were classified. The results showed there was no significant difference in the percentage of embryos development to 4-cell, 8-cell and morula (P>0.05). PLF at the doses of 10 and 100 U/mL significantly enhanced more embryos development to the blastocyst and hatching blastocyst (P 0.05). It was concluded that PLF at the concentration of 10–100 U/mL had no significant effects on the early development of mice embryos, however, PLF could promote the growth, differentiation, and hatching of preimplantion blastocysts.
