In human development, it is postulated based on histological sections, that the cardiogenic
mesoderm rotates 180° with the pericardial cavity. This is also thought to be the case in …

It is generally thought that the early pre‐tubular chick heart is formed by fusion of the anterior
or cephalic limits of the paired cardiogenic fields. However, this study shows that the heart …

In the mouse, the earliest heart precursors can be traced to approximately 50 founder cells
located on both sides of the midline in the epiblast of early gastrula stage embryos (E6 …

The mesoderm of each of the paired lateral heart-forming regions (HFRs) in the stage 5–7
chick embryo includes prospective conus (pre-C), ventricle (pre-V), and sinoatrial (pre-SA) …

The chick heart tube develops from the fusion of the right and left areas of precardiac
mesoderm and in almost all cases loops to the embryo's right-hand side. We have …

Recent molecular lineage analyses in mouse have demonstrated that the right ventricle is
recruited from anterior mesoderm in later stages of cardiac development. This is in contrast …

The contributions of right and left precardiac mesoderm to the hearts of chick embryos at
stages 9+ to 12+ have been determined. Embryos cultured by the New technique were …

Fusion of the paired cardiac primordia occurs in the right medial plane and not in the mid
sagittal plane. This feature must be considered as a result of asymetrical closing of the …

The precardiac portion of the primitive streak of the chick embryo was investigated by
placing tritiated thymidine-labeled transplants within it. The movements and final positions of …

As classically described, the precardiac mesoderm of the paired heart-forming fields migrate
and fuse anteriomedially in the ventral midline to form the first segment of the straight heart …
