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 …

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 …

The internal organs of vertebrates show specific anatomical left‐right asymmetries. The
embryonic heart is the first organ to develop such asymmetries during a process called …

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 …

The left-right asymmetry of the vertebrate heart is evident in the topology of the heart loop,
and in the dissimilar morphology of the left and right chambers. How left-right asymmetric …

The left-right body axis is defined relative to the dorsalventral and anterior-posterior body
axes. Since left-right asymmetries are not randomly oriented with respect to dorsal-ventral …

Understanding early cardiac morphogenesis, especially the process of cardiac looping, is of
fundamental interest for diverse biomedical disciplines. During the past few years …

The role of actin bundles on the heart looping of chick embryos was examined by using
cytochalasin B, which binds to the barbed end of actin filaments and inhibits association of …

The heart and viscera of vertebrates are formed from primordia that are apparently bilaterally
symmetrical. This symmetry is broken during development, yielding organs that develop …

In the embryonic heart development of mammals and birds, a straight initial heart tube
undergoes left-handed helical looping, which is a remarkable and puzzling event. We are …
