Extraembryonic Endoderm cells as a model of endoderm development

Development Growth and Differentiation, 2013
In 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.

Visceral Endoderm Mediates Forebrain Development by Suppressing Posteriorizing Signals

Developmental Biology, 2000
The anterior visceral endoderm (AVE) has attracted recent attention as a critical player in mouse forebrain development and has been proposed to act as “head organizer” in mammals.

Prospective isolation and global gene expression analysis of definitive and visceral endoderm

Developmental Biology, 2007
In spite of the therapeutic importance of endoderm derivatives such as the pancreas, liver, lung, and intestine, there are few molecular markers specific for early endoderm.

Endoderm and heart development [PDF]

Developmental Dynamics, 2000
Since the first half of the 20th century, experimental embryologists have noted a relationship between endoderm cells and the development of cardiac tissue from mesoderm. During the past decade, the accumulation of evidence for an obligatory interaction between endoderm and mesoderm during the specification and terminal differentiation of myocardial ...

Endoderm Specification and Differentiation in Xenopus Embryos

Developmental Biology, 2001
It is known from work with amniote embryos that regional specification of the gut requires cell–cell signalling between the mesoderm and the endoderm. In recent years, much of the interest in Xenopus endoderm development has focused on events that occur ...

The Endoderm

2023
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 ...

BMP4 signaling directs primitive endoderm-derived XEN cells to an extraembryonic visceral endoderm identity

Developmental Biology, 2012
The visceral endoderm (VE) is an epithelial tissue in the early postimplantation mouse embryo that encapsulates the pluripotent epiblast distally and the extraembryonic ectoderm proximally.

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,

The Guts of Endoderm Formation

2002
In this chapter, we will review the formation of the definitive endoderm, the population of cells that give rise to the lining of the digestive tract, its associated organs and the pharyngeal pouches. At the cellular level, we will describe the location and movement of endodermal cells from the onset of epiboly until the end of gastrulation.

Origin and development of the zebrafish endoderm

Development, 1999
Abstract The segregation of cells into germ layers is one of the earliest events in the establishment of cell fate in the embryo. In the zebrafish, endoderm and mesoderm are derived from cells that involute into an internal layer, the hypoblast, whereas ectoderm is derived from cells that remain in the outer layer, the epiblast.
