The researchers first used a multi-step process of genetic and biochemical manipulation that included the genes FGF, TGF and WNT, which transformed human induced pluripotent stem cells (iPS) into CDX2-positive posterior gut endodermal progenitor cells (PGECs).
Because nutrients often accumulate against a concentration gradient in the root xylem vessels, vascular plants have evolved a physical barrier that prevents passive apoplastic diffusion of ions and water across the endodermal cells surrounding the vascular bundles.
Presence of ectopic thyroid tissues at uncommon locations may be due to abnormal migration of heterotrophic differentiation of uncommitted endodermal cells.
YSTs, also known as endodermal sinus tumors, are malignant germ cell tumors that occur usually in the ovary and rarely in the endometrium.
However, function they must have not only because that's nature's way but also because they are widely expressed, in endodermal origin tissues of more ancient species such as amphibians and reptiles while also being expressed in ecto- and mesodermal tissues of more recently evolved species such as rodents and primates.

These tumours may contain mature tissue of ectodermal (skin, brain), mesodermal (muscle, fat) and endodermal (mucinous or ciliated epithelium) origin.
Yolk sac tumors, also known as endodermal sinus tumors, are large, encapsulated masses seen in young females (10-30 years) with elevated AFP.

It has been shown that the simple cuboidal endodermal epithelium transforms into a pseudostratified columnar epithelium to form the liver diverticulum in this developmental period, which corresponds to the intrauterine 8.
Thyroglossal duct is an endodermal diverticulum whose origin, foramen caecum, is located between the bases for the development of tongue, that is, in front of the copula, to be more specific.
Uncommon malignant germ cell neoplasms include immature teratomas and endodermal sinus tumors.
