Surface mesoderm in Xenopus: a revision of the stage 10 fate map
Autor: S. B. Minsuk, R. E. Keller
Publikováno v: Development genes and evolution. 207(6)
We have used two complementary cell labeling techniques to investigate dorsal mesoderm formation in Xenopus laevis and Hymenochirus boettgeri. Epithelial grafts from fluorescently labeled donors into unlabeled hosts demonstrate that in Xenopus, as pr

Absence of a clinical correlation for complement-mediated, infection-enhancing antibodies in plasma or sera from HIV-1-infected individuals. Multicenter AIDS Cohort Study Group

Publikováno v: AIDS (London, England). 5(5)
Neutralizing and complement-mediated infection-enhancing antibodies to HIV-1 were measured in sera or plasma from 54 HIV-1-positive individuals at various stages of disease, and from an additional 36 HIV-1-positive individuals for whom no clinical da

Time-lapse cinemicrographic analysis of superficial cell behavior during and prior to gastrulation inXenopus laevis
Autor: R. E. Keller
Publikováno v: Journal of Morphology. 157:223-247
Time-lapse cinemicrography was used to show what changes in the number, size, shape, arrangement and what movements of apices of superficial cells occur during epiboly, extension, convergence and blastopore formation in the blastula or gastrula of Xe

An experimental analysis of the role of bottle cells and the deep marginal zone in gastrulation ofXenopus laevis
Autor: R. E. Keller
Publikováno v: Journal of Experimental Zoology. 216:81-101
Earlier work suggested that the change in shape or the active migration of the bottle cells in the amphibian blastoporal region results in an invagination that comprises a major part of gastrulation. In the present study of gastrulation in Xenopus la

An atlas of notochord and somite morphogenesis in several anuran and urodelean amphibians
Autor: B. Woo Youn, R. E. Keller, George M. Malacinski
Publikováno v: Development. 59:223-247
A scanning electron microscopic, comparative survey of notochord and somite formation including some details of change in cell morphology and arrangement, was made of selected stagesof twospecies of anuranamphibians(Xenopuslaevis and Ranapipiens) and

The cellular basis of epiboly: An SEM study of deep-cell rearrangement during gastrulation in Xenopus laevis
Autor: R. E. Keller
Publikováno v: Development. 60:201-234
Measurements of several indices of shape, contact, position and arrangement of deep cells in the late blastula and gastrula were made from scanning electron micrographs of carefully staged, fractured embryos in order to describe the cellular processe

The Cellular Basis of Gastrulation inXenopus laevis: Active, Postinvolution Convergence and Extension by Mediolateral Interdigitation
Autor: R. E. Keller
Publikováno v: American Zoologist. 24:589-603
Time-lapse videomicrographic and SEM analyses of normal and microsurgically altered gastrulation show that the morphogenetic movements of the dorsal marginal zone (DMZ)—extension, convergence, and involution—all result from behavior that occurs a
