Epithelial tube morphogenesis during Drosophila tracheal development requires Piopio, a luminal ZP protein

Anna Ja|[zacute]|wi|[nacute]|ska , Carlos Ribeiro & Markus Affolter

The formation of branched epithelial networks is fundamental to the development of many organs, such as the lung, the kidney or the vasculature. Little is known about the mechanisms that control cell rearrangements during tubulogenesis and regulate the size of individual tubes.
