Cleavage and Gastrulation in Drosophila Embryos
The cytoskeleton guides early embryogenesis in Drosophila, which is characterized by a series of rapid synchronous syncytial nuclear divisions that occur in the absence of cytokinesis. Following these divisions, individual cells are produced in a process called cellularization, and these cells are rearranged during the process of gastrulation to produce an embryo composed of three primordial ti...
متن کاملTemporal pattern of cleavage and the onset of gastrulation in amphibian embryos developed from eggs with the reduced cytoplasm.
Fertilized eggs of the Japanese newt, Cynops pyrrhogaster, were divided into two or four equal-sized parts with fine glass rods before the first cleavage. In such cases one of the egg fragments, at least, proceeds to cleavage and gastrulates. The temporal pattern of cell division and the onset of gastrulation in such half or quarter embryos were investigated and compared with normal development...
متن کاملMitosis-specific monoclonal antibodies block cleavage in amphibian embryos.
By microinjecting monoclonal antibodies that bind specifically to mitotic and meiotic cells of a variety of species, we studied the biological activity of antigens recognized by these antibodies. The antibodies recognize a family of phosphoprotein antigens that are found throughout the cytoplasm of mitotic cells and particularly at microtubule organizing centers, including centrosomes and kinet...
متن کاملStudies on the gastrulation of amphibian embryos: pseudopodia in the gastrula of Bufo bufo japonicus and their significance to gastrulation.
The course of gastrulation in embryos of Bufo bufo japonicus was studied by use of 1 /*m Epon sections. Tt was observed that the cells of the presumptive pharyngeal endoderm and mesoderm form pseudopodia coinciding with their invagination. Some of the inner cells of the ectodermal layer also form pseudopodia. The cells of the endodermal mass and the surface of the embryo rarely form such struct...
متن کاملGastrulation in amphibian embryos, regarded as a succession of biomechanical feedback events.
Gastrulation in amphibian embryos is a composition of several differently located morphogenetic movements which are perfectly coordinated with each other both in space and time. We hypothesize that this coordination is mediated by biomechanical interactions between different parts of a gastrulating embryo based upon the tendency of each part to hyper-restore the value of its mechanical stress. ...
