Analysis of a variant without lysine in the intracellular domain reveals a ubiquitylation-independent signalling activity of the DSL ligand Delta and novel functions of the Neuralized and Mindbomb1 E3-ligases during Notch signalling.
Cytonemes mediate, and are essential for, Wingless signaling from the Drosophila wing disc to disc-associated myoblasts and for Delta-Notch signaling from these myoblasts to the dorsal air sac primordium.

Notch ligands from the Delta and Jagged families have distinct roles in epithelial progenitor cell fate of extrapulmonary and intrapulmonary airways and differentially restrict expansion of the neuroendocrine microenvironment.

Multiphoton live-imaging illuminates the dynamic underpinnings of how different types of progenitor cells migrate and interact to robustly build the mammalian Dentate Gyrus neural circuitry and new outer neurogenic niche.

Regions outside the major receptor binding interface of DLL1 and DLL4 contribute to context-dependent divergence of ligand function in vivo and differential Notch1 and Notch2 activation in vitro.
Cells of the xanthophore lineage form projections that allow them to communicate with other pigment cells during adult pigment pattern formation in zebrafish, but not in the closely-related pearl danio.
