New York Times "He has now applied the technique to human cells, starting with embryonic stem cells. The cells, he and colleagues say in the current issue of Cell, are controlled by a triumvirate of three transcription factors, known as oct4, sox2 and nanog.
MIT "The transcription factors Oct4, Sox2, and Nanog have essential roles in early development and are required for the propagation of undifferentiated embryonic stem (ES) cells in culture. To gain insights into transcriptional regulation of human ES cells, we have, in collaboration with the Young lab, identified Oct4, Sox2, and Nanog target genes using genome-scale location analysis. We found, surprisingly, that Oct4, Sox2, and Nanog co-occupy a substantial portion of their target genes. These target genes frequently encode transcription factors, many of which are developmentally important homeodomain proteins. Our data also show that Oct4, Sox2, and Nanog collaborate to form regulatory circuitry in ES cells consisting of autoregulatory and feedforward loops."
