1. Genetic dissection of tubulogenesis in the Drosophila trachea
Sammanfattning : The formation of branched tubular organs, such as the mammalian lung kidney and vascular system, is an essential process in animal development. The Drosophila tracheal (respiratory) system provides a genetic model system to study the highly ordered process of branch outgrowth and fusion required to form continuous tubular networks. LÄS MER
2. Embryonic ecdysone-induced gene expression and progression of organ morphogenesis
Sammanfattning : The formation of an epithelial organ requires a set of organ-specific gene programs that instruct parallel and successive developmental events. Still, it is unclear what are the core regulatory programs and how such programs are timely coordinated within the organ. LÄS MER
3. Genetic and molecular regulation of epithelial tube morphogenesis
Sammanfattning : 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. LÄS MER
4. Molecular regulation of epithelial tube size
Sammanfattning : 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. LÄS MER
5. Regulation of spontaneous tone in guinea pig trachea
Sammanfattning : Asthma is a common disease, characterized by periods of bronchoconstriction of unclear origin. This thesis examines a specific behavior of airway smooth muscle, the so-called spontaneous airway tone. It was suspected that a defect regulation of this tone may be a cause of asthmatic bronchoconstriction. LÄS MER
