Cell movements during epiboly and gastrulation in zebrafish
Development, 1990Abstract Beginning during the late blastula stage in zebrafish, cells located beneath a surface epithelial layer of the blastoderm undergo rearrangements that accompany major changes in shape of the embryo. We describe three distinctive kinds of cell rearrangements.

Epiboly is a crucial morphogenetic process during early animal embryogenesis that expands surface area of embryonic tissues while thinning them. During zebrafish development, epiboly spreads the superficial enveloping layer (EVL), germ layers, and yolk ...

Although steroids have numerous functions--regulating electrolyte balance; carbohydrate, protein, and fat metabolism; the inflammatory response; and the development and maintenance of secondary sex characteristics--their role during early embryogenesis has been unclear. Hsu et al.

Rho mediates cytokinesis and epiboly via ROCK in zebrafish
Molecular Reproduction and Development, 2005To study the regulation of embryonic development by Rho, we microinjected Clostridium botulinum C3-exoenzyme (C3) into zebrafish embryos. We found that C3 inhibited cytokinesis during early cleavages. C3 inhibition appeared to be specific on RhoA, since the constitutively active RhoA could partially rescued the C3-induced defects.

Cell mixing during early epiboly in the zebrafish embryo
Developmental Genetics, 1995AbstractDescendants of early blastomeres in the zebrafish come to populate distinctive regions of the fate map. We present a model suggesting that the distribution of cells in the early gastrula (the fate map stage) results from the passive response of cells to reproducible forces that change the overall shape of the blastoderm just prior to ...

Life at the Edge: Epiboly and Involution in the Zebrafish
2002In the developing zebrafish, the mid-blastula stage embryo finds itself organized as an abashed mass of blastomeres on top of a large yolk cell. Over the next few hours, these cells begin a beautiful sweep over the yolk cell as they form the germ layers.

Imaging intercellular calcium waves during late epiboly in intact zebrafish embryos
Zygote, 2003Through the injection of f-aequorin and the use of a photon imaging microscope, we have previously reported that a rhythmic series of intercellular Ca2+ waves circumnavigate zebrafish embryos over a 10 h period during gastrulation and axial segmentation.

Membrane microdomain formation is crucial in epiboly during gastrulation of medaka
Biochemical and Biophysical Research Communications, 2007Membrane microdomain (microdomain) was isolated from early gastrula embryos. The isolated microdomain was characterized by enrichment of cholesterol and sphingomyelin, and by the presence of huge glycoproteins containing Lewis X structure. Importance of the microdomain in the progress of epiboly was assessed using methyl beta-cyclodextrin (MBCD) and C2-
