    • The Blastoderm in Chicks During Early Gastrulation 

      Michaels, Chinami (Arizona State University. School of Life Sciences. Center for Biology and Society. Embryo Project Encyclopedia.Arizona Board of Regents, 2014-02-26)
      This image shows a chicken (Gallus gallus) embryo undergoing gastrulation in stage four (18-19 hrs after laying) according to the Hamburger-Hamilton staging series. At this point in time the chicken embryo is a blastoderm ...
    • A Fate Map of the Chick Embryo 

      Michaels, Chinami (Arizona State University. School of Life Sciences. Center for Biology and Society. Embryo Project Encyclopedia.Arizona Board of Regents, 2014-02-26)
      A 3-D fate map of the chicken (Gallus gallus) embryo with the prospective point of ingression and yolk. The area where the primitive streak will form during gastrulation is shown. The anterior- posterior axis is shown by ...
    • Frog Embryo in the Blastula Stage 

      Michaels, Chinami (Arizona State University. School of Life Sciences. Center for Biology and Society. Embryo Project Encyclopedia., 2013-12-13)
      Illustration of the animal-vegetal gradient in Xenopus laevis ( African clawed frog) eggs after fertilization. During fertilization, the sperm s point of entry determines the future dorsal side (shaded) and ventral side ...
    • The Process of Gastrulation in Frog Embryos 

      Michaels, Chinami (Arizona State University. School of Life Sciences. Center for Biology and Society. Embryo Project Encyclopedia., 2013-12-13)
      Illustration of the movement of the three hemispheres of cells, the animal cap (dark green) the marginal zone (lime green) and the ventral cap (yellow) during frog gastrulation. The external view column (images a.1-a.6) ...
    • Some of the Cells that Arise from Animal Gastrulas with Three Germ Layers 

      Michaels, Chinami (Arizona State University. School of Life Sciences. Center for Biology and Society. Embryo Project Encyclopedia., 2014-08-21)
      From a developing embryos three primary germ layers, ectoderm (green), mesoderm (pink) and endoderm (yellow), a variety of differentiated cell types and organ systems arise, far more than are shown here. The three primary ...
