Diabetes is characterized by loss or dysfunction of pancreatic β-cells. Here the authors show that the signalling protein WNT4 is heterogeneously activated by β-cells during their postnatal maturation with WNT4 positive cells being more mature, and that inactivating WNT4 in β-cells after maturation impairs beta-cell function.
