Coronary arteries bring blood flow to the heart muscle. Understanding the developmental program of the coronary arteries provides insights into the treatment of coronary artery diseases. Multiple sources have been described as contributing to coronary arteries including the proepicardium, sinus venosus (SV), and endocardium. However, the developmental(More)
Aortic arch interruptions in humans and animal models are mainly caused by aberrant development of the fourth pharyngeal arch artery. Little is known about the maturation of this vessel during normal and abnormal development, which is the subject of this study. Tgfbeta2 knockout mice that present with fourth artery defects have been associated with(More)
The epicardium and dorsal mesocardium are known to be the source of structures that form the wall of the coronary vessels. Because mouse knockout studies have shown that proper epicardial formation is also essential for myocardial development, we have studied in detail the migration and differentiation of epicardium-derived cells (EPDCs) within the(More)
Changes in the distribution of extracellular matrix components have been investigated immunohistochemically during neural crest development in the rat. Inside the ectodermal epithelium basal lamina components are formed resulting in a separation of neurectoderm and epidermal ectoderm. Within the presumptive neural crest area fibronectin, hyaluronan and(More)
BACKGROUND Transforming growth factor-beta(2) (TGF-beta(2)) is a member of a family of growth factors with the potential to modify multiple processes. Mice deficient in the TGF-beta(2) gene die around birth and show a variety of defects of different organs, including the heart. METHODS AND RESULTS We studied the hearts of TGF-beta(2)-null mouse embryos(More)
Recently, debate has arisen about the usefulness of cell tracking using iron oxide-labeled cells. Two important issues in determining the usefulness of cell tracking with MRI are generally overlooked; first, the effect of graft rejection in immunocompetent models, and second, the necessity for careful histological confirmation of the fate of the labeled(More)
The vagal neural crest adjacent to the first seven somites gives rise to both ganglionic and ectomesenchymal derivatives. Ganglionic derivatives are the neurons and supportive cells of the enteric nervous system (ENS), cardiac, and dorsal root ganglia. Ectomesenchymal derivatives are cells in the cardiac outflow tract and the mesenchymal components of(More)
In the development of a functional myocardium and formation of the coronary vasculature, epicardium-derived cells play an essential role. The proepicardial organ contributes to the developing coronary system by delivering mural cells to the endothelium-lined vessels. In search of genes that regulate the behavior of (pro)epicardial cells, the Ets-1 and Ets-2(More)
OBJECTIVE The number of patients with congenital heart disease who survive to adolescence and adulthood continues to increase. We review our experience with noninfectious intracranial aneurysms and cervicocephalic arterial dissections in patients with congenital heart disease, expanding the clinical spectrum of the cerebrovascular abnormalities that may be(More)
OBJECTIVE Maternal hypercholesterolemia is associated with a higher incidence and faster progression of atherosclerotic lesions in neonatal offspring. We aimed to determine whether an in utero environment exposing a fetus to maternal hypercholesterolemia and associated risk factors can prime the murine vessel wall to accelerated development of(More)
