Gprk2 adjusts Fog signaling to organize cell movements in Drosophila gastrulation.
Gastrulation of Drosophila melanogaster proceeds through sequential cell movements: ventral mesodermal (VM) cells are induced by secreted Fog protein to constrict their apical surfaces to form the ventral furrow, and subsequently lateral mesodermal (LM) cells involute toward the furrow. How these cell movements are organized remains elusive. Here, we observed that LM cells extended apical protr...
متن کاملVertebrate gastrulation: Calcium waves orchestrate cell movements
A recent study reveals that the propagation of intercellular calcium signals is closely associated with the generation of convergent extension movements during Xenopus gastrulation. Such signals provide a mechanism whereby large populations of cells can communicate to generate orchestrated cell movements.
متن کاملCell shape changes during gastrulation in Drosophila.
The first morphogenetic movement during Drosophila development is the invagination of the mesoderm, an event that folds a one-layered epithelium into a multilayered structure. In this paper, we describe the shape changes and behaviour of the cells participating in this process and show how mutations that change cell fate affect this behaviour. We divide the formation of the mesodermal germ laye...
متن کاملEmbryo-scale tissue mechanics during Drosophila gastrulation movements
Morphogenesis of an organism requires the development of its parts to be coordinated in time and space. While past studies concentrated on defined cell populations, a synthetic view of the coordination of these events in a whole organism is needed for a full understanding. Drosophila gastrulation begins with the embryo forming a ventral furrow, which is eventually internalized. It is not unders...
متن کاملThe G protein-coupled receptor regulatory kinase GPRK2 participates in Hedgehog signaling in Drosophila.
Signaling by Smoothened (Smo) plays fundamental roles during animal development and is deregulated in a variety of human cancers. Smo is a transmembrane protein with a heptahelical topology characteristic of G protein-coupled receptors. Despite such similarity, the mechanisms regulating Smo signaling are not fully understood. We show that Gprk2, a Drosophila member of the G protein-coupled rece...
