Effects of low concentrations of CrCl₃ on the quality of blastocysts. (A) Representative images of CDX2, NANOG, and DAPI staining of blastocysts exposed to low concentrations of CrCl₃ or no CrCl₃. (B and C) Quantification of total cell number (B) and ICM:TE ratio (C) of detected blastocysts in each group. (D) Representative images of EdU staining of blastocysts exposed to low concentrations of CrCl₃ or no CrCl₃. (E) Quantification of EdU-positive cells of detected blastocysts in each group. * P < 0.05; ** P < 0.01. Three independent experiments were performed.
