Efficient Neural Differentiation of hPSCs by Extrinsic Signals Derived from Co-cultured Neural Stem or Precursor Cells.

ABSTRACT: In this study, we found that undifferentiated human pluripotent stem cells (hPSCs; up to 30% of total cells) present in the cultures of neural stem or precursor cells (NPCs) completely disappeared within several days when cultured under neural differentiation culture conditions. Intriguingly, the disappearance of undifferentiated cells was not due to cell death but was instead mediated by neural conversion of hPSCs. Based on these findings, we propose pre-conditioning of donor NPC cultures under terminal differentiation culture conditions as a simple but efficient method of eliminating undifferentiated cells to treat neurologic disorders. In addition, we could establish a new neural differentiation protocol, in which undifferentiated hPSCs co-cultured with NPCs become differentiated neuron
