  • Invagination

    Intussusception is a medical condition in which a part of the intestine folds into the section immediately ahead of it. This buckles inwards towards the blastocoel in a process called invagination. Although gastrulation patterns exhibit enormous variation throughout the animal kingdom, they are unified by the five basic types of cell movements that occur during gastrulation: 1) invagination 2 ...

    This strong deviation toward the right leads to delamination of the falx cerebri, as it approaches the internal occipital crest. This situation gives rise to the formation of several laminae. One or more of these would contain the superior sagittal sinus, whereas the rest of these laminae reflect the falx cerebri attachment at the right margin of the sagittal crest. The superior sagittal sinus ...

    29/11/2016· EMBRYOLOGY. The word embryo is derived from the Gr. ἔμβρυον, which signified the fruit of the womb before its strict sense, therefore, embryology is the study of the intrauterine young or embryo, and can only be pursued in those animals in which the offspring are retained in the uterus of the mother until they have acquired, or nearly acquired, the form of the parent.

  • Gastrulation |authorSTREAM

    Delamination is the splitting of one layer into 2 different layers. Different combinations of these basic movements yield a variety of changes that characterize gastrulation. PowerPoint Presentation: How do individual cells move during gastrulation? Seven basic types of cell movement lead to the changes in epithelial sheets that characterize gastrulation. 1. Migration is the movement of an ...

    Delamination describes the movement by which an individual epithelial cell constricts apically, dislocates the nucleus basally, loses its contact to the junctional adhesive complex of neighboring epithelial cells, and slides to the basal surface of the epithelium. In ingression, the same cellular movements as in delamination occur in a group of contiguous cells. Invaginating cells start out by ...

    We analyzed Pax3 (splotch)Myf5 (targeted with nlacZ), and splotch/Myf5 homozygous mutant mice to investigate the roles that these genes play in programming skeletal myogenesis. In splotch and Myf5 homozygous embryos, myogenic progenitor cell perturbations and early muscle defects are distinct. Remarkablysplotch/Myf5 double homozygotes have a dramatic phenotype not seen in the individual ...

Traditionally only a handful of organisms have been widely studied, but modern research tools are enabling researchers to extend the set of model organisms to include lessstudied and more unusual systems.

    Delamination and migration of muscle progenitor cells. Both delamination and migration depend on the presence of c‐met, a tyrosine kinase receptor which interacts with its ligand HGF, also called scatter factor, produced by non‐somitic mesodermal cells which thus delineate the migratory route (Dietrich et al. 1999).In mutant mouse embryos which lack functional c‐met (Bladt et al. 1995 ...
