A panel of chimpanzee induced pluripotent stem cells (iPSCs) will help realise the potential of iPSCs in primate studies, and in combination with genomic technologies, transform studies of comparative evolution.
The differentiation decisions made by pluripotent cells depend on their exposure to appropriate extrinsic signals and also on morphogenetic events that control receptivity to those differentiation cues.
HIPPO signaling antagonizes the apical domain of polarized cells, driving cell internalization, regulated gene expression, and cell fate change during formation of pluripotent stem cell progenitors in the mouse embryo.
A role for FGF-mediated Map Kinase signaling in the retention of pluripotency underlying genesis of Neural Crest is revealed, along with a striking switch in the signaling cascades activated by FGF signaling as cells commence lineage restriction.
Building on previous work (Dye et al., 2015) showing that pluripotent stem cell derived lung organoids were immature/fetal, the current study shows that in vivo transplantation leads to mature tissue, reminiscent of adult airways.
