Results / Rate of development and embryo morphology

Rate of development and embryo morphology. Compared with those after control antibody treatments, the numbers of blastocysts (mean + standard error) that developed from in vivo-derived 1-cell-stage embryos were significantly (P < 0.05) reduced after treatment with neutralizing antibodies to EGF (27.3 + 0.8 blastocysts), TGFa (26.5 + 0.6 blastocysts), and EGFR (26.3 + 0.7 blastocysts; Table 1). Similar relative results were observed after treatment of in vitro-fertilized embryos with neutralizing antibodies to EGF (22.6 + 0.3 blastocysts), TGFa (21.5 + 0.2 blastocysts), and EGFR (21.2 + 0.6 blastocysts). Compared with that of in vivo-derived embryos, development of in vitro-fertilized embryos was poorer after immunoneutralization. Further, the numbers of blastocysts that developed after combined treatment with neutralizing antibodies to both EGF and TGFa of in vivo-derived embryos (12.6 + 0.6 blastocysts) and in vitro-fertilized embryos (11.8 + 0.4) were significantly (P < 0.01) fewer than after treatment with either control or individual neutralizing antibodies.

After combined antibody treatment, the percentage of blastocysts that developed from in vivo-derived (40%) and in vitro-fertilized (36%) embryos was no different from the percentage of blastocysts that developed from ICNI-derived (cloned) embryos (35%). Further, after immunoneutralization, embryos were characterized morphologically by shrinkage and fragmentation of nuclear chromatin. These changes were pronounced among in vitro-fertilized embryos after antibody treatment and in cloned embryos (Figure 1 A, D, and G). Visit our pharmacy and always enjoy the experience!
