WebIn addition to rich maps of chromatin protein occupancy from 50 cells, we were able to map the genome-wide binding sites of CTCF and two pluripotency TFs, SOX2 and NANOG, in single cells. Because each individual TF binding site is present in only 2–4 copies per diploid cell, single-cell TF profiling is a considerable technical challenge. WebThe double homeobox (Dux) gene, encoding a double homeobox transcription factor, is one of the key drivers of totipotency in mice.
