1. Rho-GTPases in Morphogenesis and Differentiation of the Developing Pancreas
Abstract : Branched tubular networks constitute the basic structure of many organs to increase surface area and to transport fluids and gases. Glandular organs such as the pancreas arise from multilayered epithelium, which undergoes de novo lumen formation and extensive remodeling and branching. READ MORE

2. Molecular regulation of epithelial tube size
Abstract : In nature, epithelial tubes are vital structures in organ design and are required for transport of gases and liquids in organs, such as the vascular system, the vertebrate lung and the kidneys. The tubular epithelium is single layered, but is often reinforced by layers of muscular support. READ MORE

3. Genetic and molecular regulation of epithelial tube morphogenesis
Abstract : Networks of epithelial tubes, such as the vertebrate lung, kidney and vascular system, enable transport of gases and nutrients to all tissues in the body. These tubes are built up by a single layer of polarized epithelial cells, with the apical membrane facing the lumen. READ MORE

4. Regulation of epithelial morphogenesis in Drosophila by the Emp scavenger receptor
Abstract : The respiratory system of Drosophila melanogaster, the trachea, is widely used as a model system to study the development of branched tubular organs. Airway maturation in Drosophila entails a series of sequential events: first, a massive apical secretion of luminal proteins initiates diametric tube expansion, second an endocytic wave removes luminal proteins and finally liquid clearance and gas filling converts the nascent epithelial tubes to a functional respiratory organ.

5. New roles for apical secretion and extracellular matrix assembly in Drosophila epithelial morphogenesis
Abstract : Branched tubular organs, such as the lung and vascular system fulfill the respiratory needs of most animals. Optimal tissue function relies on the uniform sizes and shapes of the constituting branches in each organ. READ MORE
