    The hypoblast is a tissue type that forms from the inner cell mass. It lies beneath the epiblast and consists of small cuboidal cells. Extraembryonic endoderm is derived from the epiblast which displaces the hypoblast cells. The absence of hypoblast results in multiple primitive streaks in chicken embryos.
