Directed differentiation of endodermal cells from mouse embryonic stem cells
Pluripotent embryonic stem cells hold a great promise as an unlimited source of tissue for treatment of chronic diseases such as Type 1 diabetes and chronic liver disease. Various attempts have been made to produce cells that can serve as precursors for pancreas and liver. By using …

Localization of Calbindin-D<sub>28k</sub> in Extra-Embryonic Membranes of Two Oviparous Scincid Lizards.
… calcium binding protein found in a variety of cells that transport calcium. The chorioallantoic membrane and yolk sac of oviparous squamate reptiles (lizards and snakes) transport calcium from the eggshell and yolk to the developing embryo. I used immunohistochemistry to localize …

Investigation on gravity sensing in garden cress seedlings /
… real and simulated microgravity the growth of endodermal cells in hypocotyls is slower, the location of amyloplasts changes significantly with respect to the morphological bottom of statocytes in roots and hypocotyls. The logarithmic dependence between the positioning of amyloplasts along …

WHO: A Novel Wuschel-Like Homeodomain Transcription Factor in Arabidopsis
… that the WHO gene is expressed in mature guard cells, stipules and cells surrounding the root vasculature. The overexpression mutant who, identified by transposon gene trap screening, exhibited a severely stunted phenotype. Pleiotropic defects were observable in the shoot meristem, the floral …

Epigenetic Regulation Controls Intrinsic and Extrinsic Drivers of Gastrointestinal Development
… tube known as the primitive gut tube. Endodermal cells lining the inside of the gut tube differentiate into the functional epithelial units of the gastrointestinal system. Mesodermal cells surround the endodermal layer and eventually develop into an array of mesenchymal cells which …

Anatomical, developmental and physiological aspects of silica in wheat
… to Si+ solution, but by day 10 up to 80% of endodermal cells in the basal area of the root were silicified. The percentage of silicified cells increased from the apex to the base of the root. Silica in T. aestivum was measured quantitatively using a molybdate blue detection method. Typically, …

Characterization of foetal hepatic cells during rat liver development
Die Leber entwickelt sich als Leberknospe aus dem Entoderm des unteren Abschnittes des Vorderdarmes. Die Leberknospe differenziert sich in 2 Teile: In den Leberteil und in den Galleteil. Während der embryonalen Entwicklung differenzieren sich die entodermalen Zellen zu Hepatoblasten, die sich zu …
