Specimen 4A m-/- female: embryonic day 3.5; Eedtm1d(EUCOMM)Wtsi/Eed+ (more )
Note: Tg(Zp3-cre)93Knw was used to delete the Eed floxed allele in the female germline.
Structure Level Pattern Image Note
TS4: blastocyst Present 4A middle right , 4A middle A small percentage of nuclei with H3K27me3 enrichment coinciding with the Xist RNA coat, likely due to the expression of zygotic Eed.

Note: Tg(Zp3-cre)93Knw and Tg(Prm-cre)58Og were used to delete the Eed floxed allele in both the female and male germline.
Structure Level Pattern Image Note
TS4: blastocyst Present 4A lower , 4A lower right But there was no nuclei with H3K27me3 enrichment coinciding with the Xist RNA coat, likely due to no expression of zygotic Eed.
