The ability of induced pluripotent stem cells (iPSCs) to differentiate into all adult cell types makes them attractive for research and regenerative medicine; however, it remains unknown when and how this capacity is established. We characterized the acquisition of developmental pluripotency in a suitable reprogramming system to show that iPSCs prior to passaging become capable of generating all tissues...
The differentiated state of somatic cells provides barriers for the derivation of induced pluripotent stem cells (iPSCs). To address why some cell types reprogram more readily than others, we studied the effect of combined modulation of cellular signaling pathways. Surprisingly, inhibition of transforming growth factor β (TGF-β) together with activation of Wnt signaling in the presence of ascorbic...
