Various model organisms such as mouse, xenopus, or zebrafish embryos have been
studied in the past to gain insight into the complex processes driving normal and abnormal …

We have examined the spatial restriction of heart-forming potency in Xenopus laevis
embryos, using an assay system in which explants or explant recombinates are cultured in …

Amphibian embryos are an excellent model system for analyzing the mechanisms of
vertebrate cardiogenesis. Studies of heart development in Xenopus have, for example …

The heart is the first organ to form during embryogenesis and its circulatory function is critical
from early on for the viability of the mammalian embryo. Developmental abnormalities of the …

This paper summarizes the development of the heart from the formation of the heart
mesoderm to cardiac septation. A brief account of morphological changes is provided, but …

Fate maps are required to address questions about the commitment and differentiation of
precardiac cells. Here, we report a detailed study of the precardiac cells located at the level …

Heart formation provides an excellent model studying the molecular basis of cell
determination in vertebrate embryos. By combining molecular assays with the experimental …

Scanning electron microscopy was used to study the morphogenesis of the primitive
embryonic chick heart (stage 5 late primitive streak through stage 9+). Components of the …

The primary ring, a horseshoe-shaped structure situated between the left and right ventricle
and connected superiorly to the atrioventricular canal, is the first specialized fast ventricular …

Cardiac progenitor cells in avian and amphibian embryos are known to commit to cardiac
lineage during gastrulation or early neurulation. These cells require cell interaction with …
