Online Cover This week features a Research Article that describes how fibroblast growth factor receptor 1 (FGFR1) attenuates endothelial-to-mesenchymal transition (EndMT) by inhibiting transforming growth factor–β (TGFβ) signaling in endothelial cells. The image shows that TGFβ signaling, as indicated by immunostaining for phosphorylated Smad2 (red), is minimal in endothelial cells (green) in a normal human artery. [Image: P.-Y.
