Extended Data Fig. 5. Esrrb KO clones characterisation.
a: Left: Bar plot showing the number of AP positive colonies after clonal assay of cells with loxP sites flanking the second exon of both alleles of Esrrb (Esrrb fl/fl, dark blue) and Esrrb KO cells generated by Cre-mediated recombination (light blue), cultured in 2iL and differentiated for 24h, 48h and 72h in N2B27. Mean +/- SD of n=3 independent experiments, shown as dots. Right: Barplots showing expression measured by qPCR of Esrrb in Esrrb fl/fl (dark blue) and Esrrb KO (light blue) cells cultured in 2iL and differentiated for 24h, 48h and 72h. Mean of n=2 independent experiments.
b: Schematic representation of edited alleles of 3 CRISPR-generated Esrrb KO clones. The edited genome is indicated in red. The blue sequence is an insertion. Black bars indicate deletions.
c: Bright field images of 3 CRISPR-generated Esrrb KO clones, cultured in 2iL and after 48h of 2iL withdrawal. Scale bar: 300μm.
d: Barplot showing expression by RNAseq of naive markers in WT E14 cells and in 3 CRISPR-generated Esrrb KO clones. WT values were set as 1. Mean of n=2 biological replicates.
