Abstract
▪ Abstract To most people, concerns over the link between lipids and cardiovascular health most likely end with monitoring their daily consumption of dietary fats. However, it has become increasingly clear that, in addition to effects on adult cardiovascular physiology, lipids also play key roles in the formation of a functioning cardiovascular system. The lysophospholipids, lysophosphatidic acid (LPA) and sphingosine 1-phosphate (S1P), have come to the forefront as developmental and physiological regulators of the cardiovascular system. In this review, we discuss the function of the G protein–coupled receptors responsible for transducing LPA and S1P signals during development of the vertebrate cardiovascular system, focusing first on their role in angiogenesis and then on their function during embryonic development.
