A study reveals how the Wingless signalling pathway shapes the embryonic intestine of the Drosophila fly, activating a mechanism involved in calcium transport. The finding redefines the role of ...

During embryonic development, the intestine of the Drosophila fly divides into distinct chambers thanks to the formation of constrictions at specific points of the tissue. The Wingless (Wg ...

But what genes create these signals, and how do they work? Interestingly, Wg (wingless) protein acts in the anterior wing cells just as Dpp acts in the posterior ones. In addition, each of these ...

The Drosophila embryo's midgut forms with an endodermal layer (green) encased by visceral mesoderm (blue). Three constrictions divide the gut, with Wingless (magenta) shaping the middle one.
