Gotta Have GATA for Human Pancreas Development

Haploinsufficient GATA6 mutations are associated with human pancreatic agenesis. Shi et al. (2017) in this issue of Cell Stem Cell and Tiyaboonchai et al. (2017) in a recent issue of Cell Reports utilize hPSCs to characterize GATA6 function during human pancreas development. One functional copy of GATA6 is sufficient for definitive endoderm development and pancreas formation, but it is inadequate for functional β cell differentiation.
