(A and B) Heatmap showing the dynamics of OC (A) and OO (B) DHSs during preimplantation development analyzed by liDNase-seq (left) and ATAC-seq (right). Each row represents a locus (DHS center ± 5 kb), and the red and blue gradient colors represent the liDNase-seq and ATAC-seq signal intensity, respectively. OC DHSs were separated into two groups based on whether they reappear at the morula stage (FC[morula/cumulus] > 3, RPKM > 1, and mean RPKM > 2 in morula embryos). Peaks were ordered based on the signal intensity in cumulus cells.
(C) Averaged gene expression levels of the OO- or OC-associated genes (TSS ± 10 kb) in cumulus cells and preimplantation embryos. The p values were calculated using the Wilcoxon rank sum test.
(D) Averaged gene expression levels of the CO-associated genes (TSS ± 10 kb) in cumulus cells and preimplantation embryos. The p values were calculated using the paired t test.
