Vertebrate development: Multiple phases to endoderm formation
نویسنده
چکیده
Recent results support a two-step model for endoderm formation in amphibian embryos, in which endoderm is initially specified by localised maternal factors, including the transcription factor VegT, but is then maintained by extracellular signalling molecules of the transforming growth factor-beta family.

Retinoic Acid and the Development of the Endoderm
Retinoic acid (RA) is an important signaling molecule in the development of the endoderm and an important molecule in protocols used to generate endodermal cell types from stem cells. In this review, we describe the RA signaling pathway and its role in the patterning and specification of the extra embryonic endoderm and different endodermal organs. The formation of endoderm is an ancient evolut...
متن کاملLive imaging of heart tube development in mouse reveals alternating phases of cardiac differentiation and morphogenesis
During vertebrate heart development, two progenitor populations, first and second heart fields (FHF, SHF), sequentially contribute to longitudinal subdivisions of the heart tube (HT), with the FHF contributing the left ventricle and part of the atria, and the SHF the rest of the heart. Here, we study the dynamics of cardiac differentiation and morphogenesis by tracking individual cells in live ...
متن کاملA molecular pathway leading to endoderm formation in zebrafish
BACKGROUND Several potentially important regulators of vertebrate endoderm development have been identified, including Activin-related growth factors and their receptors; transcriptional regulators encoded by the genes Mixer, Xsox17, and HNF3beta; zebrafish One-eyed pinhead (Oep), a member of the Cripto/FRL-1/Cryptic family of epidermal growth factor related proteins (EGF-CFC); and the product ...
متن کاملReiterative expression of pax1 directs pharyngeal pouch segmentation in medaka.
A striking characteristic of vertebrate development is the pharyngeal arches, which are a series of bulges on the lateral surface of the head of vertebrate embryos. Although each pharyngeal arch is segmented by the reiterative formation of endodermal outpocketings called pharyngeal pouches, the molecular network underlying the reiterative pattern remains unclear. Here, we show that pax1 plays c...
متن کاملMolecular regulation of vertebrate early endoderm development.
Detailed study of the ectoderm and mesoderm has led to increasingly refined understanding of molecular mechanisms that operate early in development to generate cellular diversity. More recently, a number of powerful studies have begun to characterize the molecular determinants of the endoderm, a germ layer previously neglected in developmental biology. Work in diverse model systems has converge...
