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) signaling ...

Spider embryo with a loss of the waist region upon knockdown of the gene waistless. Hoechst staining with fluorescent stereomicroscopy. An ancient gene is crucial for the development of the ...

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. "We knew ...
