A human embryonic stem cell is likewise described through the expression of several transcription factors and cell floor proteins. The transcription variables Oct-4, Nanog, and Sox2 variety the core regulatory community that ensures the suppression of genes that lead to differentiation and the upkeep of pluripotency.
