2009 Lecture 7
Early Vascular Development
Introduction
This lecture will introduction to the events in early embryonic development that relate to mesoderm and early cardiovascular development. Note that we will be returning later to discuss the late development of the heart and vascular changes.
Lecture Objectives
- Understanding of mesoderm development
- Understanding of heart tube formation and early development
- Understanding of early blood vessel and blood development
- Brief understanding of vascular growth and regression
- Brief understanding of vascular growth factors

Terms
angioblast - the embryonic precursor cell which will form the walls of both arteries and veins. (More? Blood Vessel)
bulbus cordis -common outflow tract region of the early developing heart tube. Blood Pathway: sinus venosus - atrium - ventricle - bulbus cordis (outflow tract) (More? Heart Notes)
cardinal vein - name given to the initial early vessels that will form the systemic venous system. System, like most vessels are initially bilaterally symmetrical. (More? Blood Vessel Notes | Cardiovascular Notes)
cardiocyte - cardiac muscle cell.
coarctation of the aorta - (Latin coartare = to press together) Term used to describe a developmental abnormality of narrowing (stricture, constriction) of the aortic arch. (More? Coarctation of Aorta)
splanchnic mesoderm - Embryonic origin of the gastrointestinal tract connective tissue, smooth muscle,, cardiac tissue and blood vessels. In the trilaminar embryo, the portion of the lateral plate mesoderm closest to the endoderm when this mesoderm is divided by formation of the intraembryonic coelom.
