The endodermal cells of some "brown" hydra are autonomous in their ability "to host or not to host" symbiotic algae: analysis of chimera.
Importantly, it has been reported that GSO1/SGN3 is expressed in root endodermal cells and its loss-of-function mutations result in the formation of a repeatedly interrupted, discontinuous Casparian strip.
We also believe that the endodermal cells possess an additional transcriptional mechanism that finely modulates the transition between the two processes (EMT and MET), and, therefore, the prognosis will be worse in cells of endodermal origin.
SOX17 had previously been shown to be involved in directing stem cells to become endodermal cells, which then develop into cells including those for the lung, gut and pancreas, but this is the first time it has been seen in PGC specification.
Mammalian PGCs are derived from the endodermal cells of the yolk sac of the hindgut [24, 25].
We observed that endodermal cells comprise the outer cell layers of the EB, as shown by the presence of the endodermal marker GATA4 (Figure 1B).
The passage cells may be isolated or two grouped interpolated to the other endodermal cells. Lignified pericyclic cells are interspersed by two-three layers of thin-walled cells, located towards each of the nine protoxylem poles.
The main assumption postulates that the cyst forms as a result of primary adhesion of endoderm anterior to the notochord, incomplete fusion of the notochord, persistence of the neurenteric canal or formation of a split notochord and displacement of endodermal cells.5 Hemivertebrae, unsegmentation of vertebra, spina bifida, and clefts in the vertebral bodies are all vertebral abnormalities that can be associated with neurenteric cysts.
In effect, the rate of expansion of dividing endodermal cells dictates the equivalent rate in other tissues.
Whether water and mineral ions move apoplastically (between cells) or symplastically, everything entering the vascular tissue must pass through the cell membranes of the endodermal cells.
It is hoped they can be turned safely into liver and pancreas cells, known as endodermal cells, which can help the body produce the insulin many diabetics lack.
