In [[embryology]], the '''epiblast''' is a tissue type derived from the [[inner cell mass]]. 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]].
