Vertebrate Endoderm Development
Annual Review of Cell and Developmental Biology, 1999▪ Abstract Endoderm, one of the three principal germ layers, contributes to all organs of the alimentary tract. For simplicity, this review divides formation of endodermal organs into four fundamental steps: (a) formation of endoderm during gastrulation, (b) morphogenesis of a gut tube from a sheet of cells, (c) budding of organ domains from the tube,

This chapter discusses the Sox17 transcription factor, which is crucial for the specification of the endoderm that constructs the digestive (gut) tube and the respiratory tube. It analyzes the endoderm in the posterior which becomes a collection of midgut-hindgut precursor cells forming the intestines and the endoderm near the head that form the ...

Extraembryonic Endoderm cells as a model of endoderm development
Development, Growth & Differentiation, 2013In recent years the multipotent extraembryonic endoderm (XEN) stem cells have been the center of much attention. In vivo, XEN cells contribute to the formation of the extraembryonic endoderm, visceral and parietal endoderm and later on, the yolk sac.

AbstractEmbryos mostly follow a single morphogenetic trajectory, where variability is largely quantitative with no qualitative differences. This robustness stands in contrast to in-vitro embryo-like models, which, like most organoids, display a high degree of variability.

Vaginal endodermal sinus tumor
The Indian Journal of Pediatrics, 2005Malignant germ cell tumors are rare tumors of childhood accounting less than 3% of pediatric malignancies, and endodermal sinus tumor (EST) is the most common histological subtype. The vagina is an extremely rare site for germ cell tumors (GCT). A one-year female was admitted with history of bleeding per vagina.

Acta Obstetricia et Gynecologica Scandinavica, 1972
A 32‐year‐old woman, who attended regularly for follow‐up because of a carcinoma in situ of the cervix uteri, developed symptoms of a rapidly progressing malignant process in the pelvis over a period of a few months. At operation large masses of tumour were found in both ovaries as well as diffuse metastases throughout the whole abdomen, and bilateral ...

Molecular analysis of endoderm regionalization
Development, Growth & Differentiation, 2008We have engaged in a number of studies in our laboratory that have focused on the molecular mechanisms underlying gut formation, with particular attention being paid to the establishment of regional differences found in the entire gut and within each digestive organ.

Actin cytoskeleton of extraembryonic endoderm and teratocarcinoma-derived endoderm cells
Experimental Cell Research, 1989Distinct F-actin- and myosin-containing stress fibers were observed in situ in many endoderm cells of parietal yolk sacs from 11-day mouse embryos. In visceral endoderm (VE) such fibers were not seen, and F-actin was concentrated in the cell periphery.

Endodermal sinus tumor in children
Journal of Pediatric Surgery, 1996Malignant germ cell tumors account for about 3% of neoplasms in children, and endodermal sinus tumor (EST) is the most common histological subtype. The authors reviewed 22 years' experience (at their institution) in the management of 37 patients with this tumor.
