It lies above the [[hypoblast]]. In [[mammalian embryogenesis]], the [[columnar cells]] of the epiblast are adjacent to the [[trophoblast]], while the [[cuboidal cells]] of the hypoblast are closer to the [[Blastocoele]]. The epiblast, whilst referred to as the primary ectoderm, differentiates to form all three layers of the trilaminar embryonic disc in a process called [[gastrulation]]. ==See also== *[[Embryogenesis]] *[[Mammalian embryogenesis]] ==External links== * http://www.iscr.ed.ac.uk/images/tilo_kunath/Tilo-Web-figure-1.gif * http://www.embryology.ch/allemand/iperiodembry/carnegie02.html * http://www.med.umich.edu/lrc/coursepages/M1/embryology/embryo/04secondweek.htm * http://isc.temple.edu/marino/embryology/EMBII97/sld005.htm {{developmental-biology-stub}} {{Embryology}} [[de:Epiblast]] [[es:Epiblasto]] [[Category:Embryology]]
