CRISPR/Cas9 Targeting of EDNRB in isogenic iPS cells. (A) Structure of the EDNRB locus showing localization of two guides that were used to ablate all 4 isoforms. (B) Genotyping of isogenic clones after CRISPR/Cas9 editing showing EDNRB+/+, EDNRB+/− and EDNRB−/− clones. (C) FACS analysis for CD34+ generated from Cas9 edited disomic and trisomic isogenic cells. (D) Quantification of B cell production in differentiated cells, presented as number of B cells generated per input CD34+ cell (p-value ≤ 0.15, between disomic KO and disomic WT/Het). G1 and G2 refer to two guides that were used for EDNRB editing.
