Abstract

The objective of this study is to evaluate the developmental ability of mouse embryo in the presence of human amniotic fluid (hAF), The highest development rate was found in the culture media supplemented with 20% mid-term hAF but this rate was concomitantly reduced with more than 20% hAF. Furthermore, mouse two-cell embryos cultured in 20% mid-term hAF were developed more consistently to the expanded and hatched blastocyst stages compared to those cultured in simple medium. However, no significant differences in the embryo development rates were observed among the supplemented effects of 20% mid-term hAF, 0.3% bovine serum albumin (BSA), and 10% fetal calf serum (FCS), Development rates of two-ceiI mouse embryos cultured in 20% full-term hAF were declined compared to 20% mid-term hAF. Outgrowth of hatched blastocysts were observed when the embryos were cultured in medium containing 20% mid-term hAF or 10% FCS. But two-cell mouse embryos cultured in the presence of 20% full-term hAF or O.3% BSA was not observed their outgrowth. The kinetics of outgrowth processes in the presence of hAF were similar to those with 10% FCS. However, embryos with FCS showed a considerably greater extents of trophetodermal cell proliferation and outgrowth. Taken together, these data suggest that mid-term hAF may have a suitability for the mammalian embryos and induce embryonic outgrowth.
