Cell-pattern disordering during convergent extension in Drosophila
Convergent extension is the cell-rearrangement process by which a developing embryo elongates to establish the head-to-tail body axis. In the early Drosophila embryo, this process occurs within a one-cell-thick epithelial layer. Using confocal microscopy, images were collected of the two-dimensional cell pattern at four stages during convergent extension in wild-type embryos and at one stage in...
متن کاملCalcium signaling during convergent extension in Xenopus
BACKGROUND During Xenopus gastrulation, cell intercalation drives convergent extension of dorsal tissues. This process requires the coordination of motility throughout a large population of cells. The signaling mechanisms that regulate these movements in space and time remain poorly understood. RESULTS To investigate the potential contribution of calcium signaling to the control of morphogene...
متن کاملModels of convergent extension during morphogenesis
Convergent extension (CE) is a fundamental and conserved collective cell movement that forms elongated tissues during embryonic development. Thus far, studies have demonstrated two different mechanistic models of collective cell movements during CE. The first, termed the crawling mode, was discovered in the process of notochord formation in Xenopus laevis embryos, and has been the established m...
متن کاملAnisotropy Effects During Unstable Step Flow Growth
Acknowledgements First of all I would like to thank my supervisor Klaus Kassner for his overall support during the various stages of my Ph.D. studies. I am grateful for the pleasant working environment and many important learning opportunities. This work is the result of a fruitful collaboration with Laboratoire de Spec-trométrie Physique in Grenoble, where I spent numerous enjoyable research v...
متن کاملXIer2 is required for convergent extension movements during Xenopus development.
Immediate early response 2 (Ier2) is a downstream target of fibroblast growth factor (FGF) signaling. In zebrafish, Ier2 is involved in left-right asymmetry establishment and in convergent extension movements. We isolated the Xenopus ier2 gene based on sequence similarity searches using multiple vertebrate species. Xenopus Ier2 has high homology in the N-terminal region to other vertebrate Ier2...
