Assay for Transposase Accessible Chromatin with high-throughput sequencing (ATAC-seq) revealed genomic chromatin accessibilities change induced by loss of ARID1A in differentiated (day 4) H9 hESCs

We reported loss of ARID1A promoted neurogenesis and inhibited cardiogenesis. Under microscopy, we observed that spontaneously differentiated cells were induced in ARID1A KO H9 hESCs cultured in mTesR medium. We did not know what cells types were. Here ATAC-seq were used to investigate chromatin accessibilities change in differentiated (day 4) WT H9 hESCs and ARID1A KO hESC cells. Overall design: Identification of genomic chromatin accessibilities change induced by loss of ARID1A in H9 hESCs.
