WEBJun 9, 2017 · Endoderm Definition. The endoderm is an embryonic germ layer that gives rise to tissues that form internal structures and organs. The endoderm is found in both vertebrate and invertebrate embryos, and is responsible for the formation of the gut and associated organs.
Endoderm | Gastrulation, Organogenesis, Morphogenesis
WEBEndoderm, the innermost of the three germ layers, or masses of cells (lying within ectoderm and mesoderm), which appears early in the development of an animal embryo. The endoderm subsequently gives rise to the epithelium (tissue that covers, or lines, a structure) of the pharynx, including the.
Endoderm - Wikipedia
WEBEndoderm is the innermost of the three primary germ layers in the very early embryo. The other two layers are the ectoderm (outside layer) and mesoderm (middle layer). Cells migrating inward along the archenteron form the inner layer of the gastrula, which develops into the endoderm.

Endoderm development: from patterning to organogenesis
WEBMar 1, 2000 · Because signaling must occur between germ layers in order to achieve a properly organized body, our understanding of the coordinated development of all organs requires a more thorough consideration of the endoderm and its derivatives. This review focuses on present knowledge and perspectives concerning endoderm patterning and …
The endoderm: a divergent cell lineage with many commonalities
WEBJun 1, 2019 · ABSTRACT. The endoderm is a progenitor tissue that, in humans, gives rise to the majority of internal organs. Over the past few decades, genetic studies have identified many of the upstream signals specifying endoderm identity in different model systems, revealing them to be divergent from invertebrates to vertebrates.
