Mass transit: epithelial morphogenesis in the Drosophila egg chamber.
Epithelial cells use a striking array of morphogenetic behaviors to sculpt organs and body plans during development. Although it is clear that epithelial morphogenesis is largely driven by cytoskeletal rearrangements and changes in cell adhesion, little is known about how these processes are coordinated to construct complex biological structures from simple sheets of cells. The follicle cell ep...
متن کاملThree-dimensional epithelial morphogenesis in the developing Drosophila egg.
Morphogenesis of the respiratory appendages on eggshells of Drosophila species provides a powerful experimental system for studying how cell sheets give rise to complex three-dimensional structures. In Drosophila melanogaster, each of the two tubular eggshell appendages is derived from a primordium comprising two distinct cell types. Using live imaging and three-dimensional image reconstruction...
متن کاملThe Schistosome Egg in Transit
The Schistosoma mansoni egg develops in the female worm ooctype where the oocyte and surrounding vitelline granules become enclosed by a protective shell. The schisto some egg is then transported through the uterus to emerge from the genital pore of the intravascular worm. It is not known how eggs successfully enter the perivascular space and how they transit the intestinal wall into the stools...
متن کاملDrosophila egg chamber elongation
As tissues and organs are formed, they acquire a specific shape that plays an integral role in their ability to function properly. A relatively simple system that has been used to examine how tissues and organs are shaped is the formation of an elongated Drosophila egg. While it has been known for some time that Drosophila egg elongation requires interactions between a polarized intracellular b...
متن کاملDrosophila nonmuscle myosin II has multiple essential roles in imaginal disc and egg chamber morphogenesis.
Morphogenesis is characterized by orchestrated changes in the shape and position of individual cells. Many of these movements are thought to be powered by motor proteins. However, in metazoans, it is often difficult to match specific motors with the movements they drive. The nonmuscle myosin II heavy chain (MHC encoded by zipper is required for cell sheet movements in Drosophila embryos. To det...
