Fig. 5. — Effect of low-dose CrCl₃ exposure during the preimplantation stage on subsequent implantation success and post-implantation development. (A) Representative pictures of uterine morphology and implantation sites. Twelve blastocytes exposed to low concentrations of CrCl₃ or no CrCl₃ were transferred into each pseudopregnant recipient female. Implantation was determined at E4.5 by the blue dye method; each blue band indicates an implantation site. Right panel: quantification of implantation rate in each group. (B) Representative images of E7.5 embryos with normal (N) or abnormal (ABN) morphologies. Right panel: quantification of development rate of embryos with normal morphology in each group. The number (n) of embryos examined in each group is indicated.
