Human Embryonic Stem Cells - Constitutive Gene Expression and Differentiation Towards Definitive Endoderm and Posterior Foregut Endoderm
… research tools. Identification of definitive endoderm (DE) - from where pancreas originates, requires analysis methods that can detect multiple markers within individual cells, since many markers expressed in DE are also detected in extraembryonic endoderm. In this thesis, we approached single …

FGF signaling in specification of hESC-derived definitive endoderm
… Pancreas originates from the definitive endoderm (DE), one of the three germ layers. The path from definitive endoderm to pancreatic progenitor cells and finally the insulin producing beta cells involves sequential cell-fate decisions characterized by the expression of multiple …

Multiple roles of epithelial signaling during craniofacial and foregut morphogenesis
… eating arise from the pharyngeal and anterior foregut epithelium (FGE), which contains the oral ectoderm and the foregut endoderm. Proper differentiation and signaling within and from this epithelial tissue is necessary for the development of the mandible, the esophagus, and the trachea. Many …

The evolution and function of pharyngeal arch signalling centres in jawed vertebrates
… columns of tissue that form when pouches of foregut endoderm contact surface ectoderm on either side of the embryonic vertebrate head. In fishes, endodermal pouches fuse with surface ectoderm to form gill slits. Once delineated, pharyngeal arches undergo morphogenesis and differentiation, …

Mechanisms of Foregut Formation in Mus Musculus
In mice, the foregut forms by the invagination of the anterior endoderm at embryonic day 7.5 and later gives rise to essential organs of the gastrointestinal and respiratory system. The formation of the foregut is critical for establishing the anterior organisation of the embryo, including the …

Early liver formation in zebrafish: a molecular and morphological approach
… of the swim bladder - are derived from the endodermal germ layer. In zebrafish the digestive system starts out as a rod at the embryonic midline, which subsequently becomes patterned and outgrowth of its associated organs occurs. Liver formation can be subdivided into three distinct phases; …
