An excellent step 3-D future chart of chicken (Gallus gallus) embryo toward potential part away from ingression and you can yolk. The space where in fact the primitive streak have a tendency to setting throughout the gastrulation are shown. Brand new anterior- rear axis is found because of the brands new anterior and you may posterio stops (A) and (P). Other shade suggest possible fates of different areas of the brand new epiblast just after gastrulation.
So it photo reveals a chicken (Gallus gallus) embryo in the process of gastrulation for the phase four (18-19 many hours shortly after installing) according to the Hamburger-Hamilton presenting series. At this point in time the latest poultry embryo are good blastoderm (revealed in the bluish). The original magnification of the embryo implies that this new blastoderm cellphone levels has thickened to create the latest primitive streak and you may Hensen’s node.
