The control of chemotactic cell movement during Dictyostelium morphogenesis.
Differential cell movement is an important mechanism in the development and morphogenesis of many organisms. In many cases there are indications that chemotaxis is a key mechanism controlling differential cell movement. This can be particularly well studied in the starvation-induced multicellular development of the social amoeba Dictyostelium discoideum. Upon starvation, up to 10(5) individual ...
متن کاملDictyostelium: a model for regulated cell movement during morphogenesis.
Dictyostelium has played an important role in unraveling the pathways that control cell movement and chemotaxis. Recent studies have started to elucidate the pathways that control cell sorting, morphogenesis, and the establishment of spatial patterning in this system. In doing so, they provide new insights into how cell movements within a multicellular organism are regulated and the importance ...
متن کاملArchitecture and morphogenesis in the mound of Macrotermes michaelseni (Sjöstedt) (Isoptera: Termitidae, Macrotermitinae) in northern Namibia
The mounds of Macrotermes michaelseni (Sjöstedt) in northern Namibia have a characteristic architecture, being divided into three structurally distinct components: a central cone-shaped mound, topped by a tall, thin spire which tilts northward at an angle similar to the sun's average zenith angle, and a broad outwash pediment that results from erosion off the mound. Internally, the mound is per...
متن کاملLeft-right asymmetric cell intercalation drives directional collective cell movement in epithelial morphogenesis.
Morphogenetic epithelial movement occurs during embryogenesis and drives complex tissue formation. However, how epithelial cells coordinate their unidirectional movement while maintaining epithelial integrity is unclear. Here we propose a novel mechanism for collective epithelial cell movement based on Drosophila genitalia rotation, in which epithelial tissue rotates clockwise around the genita...
متن کاملCell Biology and Morphogenesis
Somatic embryos of Arabidopsis thaliana can be produced from explants of developing zygotic embryos. Cultivation of explants on maturation medium results in development of three main classes of regenerative structures: adventitious shoots, fused shoots, and complete somatic embryos. The ontogeny and anatomy of these structures was examined using serial plastic sections. Furthermore, two molecul...
