Cardiac looping in the chick embryo: A morphological review with special reference to terminological and biomechanical aspects of the looping process
  • J. Maenner
  • Biology, Medicine
  • The Anatomical record
  • 1 July 2000
Understanding early cardiac morphogenesis, especially the process of cardiac looping, is of fundamental interest for diverse biomedical disciplines. During the past few years, remarkable progress hasExpand

Does the subepicardial mesenchyme contribute myocardioblasts to the myocardium of the chick embryo heart? A quail‐chick chimera study tracing the fate of the epicardial primordium
  • J. Maenner

  • The Anatomical record
  • 1 June 1999
Morris (J. Anat., 1976;121:47–64) proposed that the subepicardial mesenchyme might represent a continuing source of myocardioblasts during embryonic and fetal development. Recent studies have shownExpand

The Origin, Formation and Developmental Significance of the Epicardium: A Review
Questions on the embryonic origin and developmental significance of the epicardium did not receive much recognition for more than a century. It was generally thought that the epicardium was derivedExpand

Lineage and Morphogenetic Analysis of the Cardiac Valves
We used a genetic lineage-labeling system to establish the material contributions of the progeny of 3 specific cell types to the cardiac valves. Thus, we labeled irreversibly the myocardialExpand

Epicardium-derived progenitor cells require β-catenin for coronary artery formation
We have previously identified several members of the Wnt/β-catenin pathway that are differentially expressed in a mouse model with deficient coronary vessel formation. Systemic ablation of β-cateninExpand

Experimental study on the formation of the epicardium in chick embryos
  • J. Maenner
  • Biology, Medicine
  • Anatomy and Embryology
  • 1 March 1993
In chick embryos, the formation of the epicardium proceeds from the attachment of a secondary sinuventricular mesocardium. This mesocardium is formed by the adhesion of pericardial villi with theExpand

The role of Wnt signalling in cardiac development and tissue remodelling in the mature heart.
The heart is one of the first organs to function in the developing embryo. Vertebrate heart development can be subdivided into different phases, e.g. specification of myo- and endocardial progenitorExpand

  • 1 January 2009
The early embryonic heart of vertebrates is a simple tubular pump. During the early phases of its development, the initially straight embryonic heart tube becomes transformed into a helically woundExpand

BMP is an important regulator of proepicardial identity in the chick embryo.
The proepicardium (PE) is a transient structure formed by pericardial coelomic mesothelium at the venous pole of the embryonic heart and gives rise to several cell types of the mature heart. In orderExpand

  • 1 May 2004
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 dextro-looping. TherebyExpand
