Blood vessel patterning at the embryonic midline.
The reproducible pattern of blood vessels formed in vertebrate embryos has been described extensively, but only recently have we obtained the genetic and molecular tools to address the mechanisms underlying these processes. This review describes our current knowledge regarding vascular patterning around the vertebrate midline and presents data derived from frogs, zebrafish, avians, and mice. Th...
متن کاملRole of neural guidance signals in blood vessel navigation.
Despite the tremendous progress achieved in both vasculogenesis and angiogenesis in the last decade, little is still known about the molecular mechanisms underlying the pathfinding of blood vessels during their formation. However, emerging evidence shows that different axonal guidance cues, including members of the Slit and semaphorin families, are also involved in the blood vessel guidance, su...
متن کاملThe Regulation of Blood Vessel Growth
The vascular system forms through a combination of vasculogenesis and angiogenesis. In vasculogenesis, vessels form de novo via the assembly of endotheial precursors called angioblasts, whereas in angiogenesis new vessels arise by migration and proliferation of endothelial cells from preexisting vessels. Although the two processes are distinct in some respects, recent evidence suggests that the...
متن کاملRegulation of lymphatic-blood vessel separation by endothelial Rac1.
Sprouting angiogenesis and lymphatic-blood vessel segregation both involve the migration of endothelial cells, but the precise migratory molecules that govern the decision of blood vascular endothelial cells to segregate into lymphatic vasculature are unknown. Here, we deleted endothelial Rac1 in mice (Tie1-Cre(+);Rac1(fl/fl)) and revealed, unexpectedly, that whereas blood vessel morphology app...
متن کاملCardiovascular Patterning as Determined by Hemodynamic Forces and Blood Vessel Genetics
BACKGROUND Vascular patterning depends on coordinated timing of arteriovenous specification of endothelial cells and the concomitant hemodynamic forces supplied by the onset of cardiac function. Using a combination of 3D imaging by OPT and embryo registration techniques, we sought to identify structural differences between three different mouse models of cardiovascular perturbation. RESULTS E...
