There was an error in Development (2018) 145, dev163014 (doi:10.1242/dev.163014).
An anonymous post on PubPeer indicated that the first two images of PdgfrαBmpr1afx/+ and PdgfrαBmpr1afx/fx cells in Fig. 3E are identical. The authors contacted us with the original data and say that they made an error during figure preparation. The corrected panel with the updated PdgfrαBmpr1afx/+ image is shown here. Analysis of the assays shown in the figure is not affected and the authors apologise for any inconvenience caused.
Effect of BMP pathway activation or inhibition in AT2 or Pdgfrα+ cells on AT2 cell behavior in organoid assays. (E) Conditional deletion of Bmpr1a in Pdgfrα+ cells has no effects on CFE or differentiation. For all experiments, n=3 animals. Scale bars: 50 μm.
