Does endoderm come from hypoblast? layer of cells, called the hypoblast, between the inner cell mass and the cavity.
The hypoblast lies beneath the epiblast and consists of small cuboidal cells. The hypoblast in fish (but not in birds and mammals) contains the precursors of both the endoderm and mesoderm. In birds and mammals, it contains precursors to the extraembryonic endoderm of the yolk sac. In chick embryos, early … See more In amniote embryology, the hypoblast, is one of two distinct layers arising from the inner cell mass in the mammalian blastocyst, or from the blastodisc in reptiles and birds. The hypoblast gives rise to the yolk sac, which in turn gives … See more Although the hypoblast does not contribute to the embryo, it influences the orientation of the embryo. The hypoblast also inhibits primitive streak formation. The absence of hypoblast results in … See more In fish, the hypoblast is the inner layer of the thickened margin of the epibolizing blastoderm in the gastrulating fish embryo. The hypoblast in fish (but not in birds or mammals) contains the precursors of both the endoderm and mesoderm.
