Figure 2From: EGF increases expression and activity of PAs in preimplantation rat embryos and their implantation rateQuantitative (Pixels/embryos) uPA expression in preimplantation rat embryos developed in-vitro with and without the presence of EGF in the medium (A). Quantitative (Pixels/embryos) tPA expression in preimplantation rat embryos developed in-vitro with and without the presence of EGF in the medium (B). Means ± SEM. Different letters above the columns represent significant differences (ANOVA followed by LSD test, P < 0.01).Back to article page
