Comparative strategies and schemes for identifying indicators that predict embryo prognosis. (a) The zygote injected with the fluorescent probe histone H2B-mCherry mRNA was observed up to the blastocyst stage. Each blastocyst was transplanted into one pseudopregnant mouse, and the comparison was made retrospectively based on the transplantation results. (b) We measured the number of nuclei, morphology, and motility using barycentric coordinates.
