During embryonic development, the intestine of the Drosophila fly divides into distinct chambers thanks to the formation of ...

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 ...

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.
