Fluid shear stress threshold regulates angiogenic sprouting.
The density and architecture of capillary beds that form within a tissue depend on many factors, including local metabolic demand and blood flow. Here, using microfluidic control of local fluid mechanics, we show the existence of a previously unappreciated flow-induced shear stress threshold that triggers angiogenic sprouting. Both intraluminal shear stress over the endothelium and transmural f...
متن کاملSyndecan-2 is essential for angiogenic sprouting during zebrafish development.
We used a morpholino-based gene-targeting screen to identify a novel protein essential for vascular development using the zebrafish, Danio rerio. We show that syndecan-2, a cell-surface heparan sulfate proteoglycan, is essential for angiogenic sprouting during embryogenesis. The vascular function of syndecan-2 is likely conserved, as zebrafish and mouse syndecan-2 show similar expression patter...
متن کاملFlow-induced HDAC1 phosphorylation and nuclear export in angiogenic sprouting
Angiogenesis requires the coordinated growth and migration of endothelial cells (ECs), with each EC residing in the vessel wall integrating local signals to determine whether to remain quiescent or undergo morphogenesis. These signals include vascular endothelial growth factor (VEGF) and flow-induced mechanical stimuli such as interstitial flow, which are both elevated in the tumor microenviron...
متن کاملCdc42 regulates branching in angiogenic sprouting in vitro.
OBJECTIVES The morphogenetic events that occur during angiogenic sprouting involve several members of the Rho family of GTPases, including Cdc42. However, the precise roles of Cdc42 in angiogenic sprouting have been difficult to elucidate owing to the lack of models to study these events in vitro. Here, we aim to identify the roles of Cdc42 in branching morphogenesis in angiogenesis. METHODS ...
متن کاملBiomimetic model to reconstitute angiogenic sprouting morphogenesis in vitro.
Angiogenesis is a complex morphogenetic process whereby endothelial cells from existing vessels invade as multicellular sprouts to form new vessels. Here, we have engineered a unique organotypic model of angiogenic sprouting and neovessel formation that originates from preformed artificial vessels fully encapsulated within a 3D extracellular matrix. Using this model, we screened the effects of ...
