...Sara Caviglia; Stefan Luschnig Cells at the tips of budding branches in the Drosophila tracheal system generate two morphologically different types of seamless tubes. Terminal cells (TCs) form branched lumenized extensions that mediate gas exchange at target tissues, whereas fusion cells (FCs) form...

... proliferation and cell cycle regulation. Using the tracheal system of Drosophila as a morphogenetic model, we have undertaken a detailed analysis of Ttk function. Ttk is autonomously and non-autonomously required during embryonic tracheal formation. Remarkably, besides a role in the specification of different...

... protein, is required for the proper morphogenesis of the Drosophila tracheal system. Homozygous embryos for Lac mutations, which we find fail to complement the previous identified bulbous (bulb) mutation, display convoluted tracheal tubes and tube breaks. At the cellular level, we can detect enlarged...

...Marta Llimargas ABSTRACT The Drosophila tracheal system consists of a stereotyped network of epithelial tubes formed by several tracheal cell types. By the end of embryogenesis, when the general branching pattern is established, some specialised tracheal cells then mediate branch fusion while...

...Chao-Kung Chen; Ronald P. Kühnlein; Karsten G. Eulenberg; Stéphane Vincent; Markus Affolter; Reinhard Schuh ABSTRACT Cell migration during embryonic tracheal system development in Drosophila requires DPP and EGF signaling to generate the archetypal branching pattern. We show that two genes encoding...
