Telomeric TRF1 controls the transcriptional programmes of pluripotent stem cells by recruiting PRC2 to pluripotency and differentiation genes by controlling the expression of those gene sites and the binding of TERRA RNAs to them.
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.
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.
Directed differentiation of stem cells can generate ventral-anterior foregut spheroids that can expand into three-dimensional lung organoids with striking structural, cellular and molecular similarities to the human fetal lung.
