Do unruptured brain vessel malformations need preventative surgery?
Normally, blood from the heart moves from the arteries to the veins through a fine network of small blood vessels called a capillary bed. In an individual with a brain AVM, the arteries and veins are connected directly without a capillary bed, exposing the ...
Positive flow: Dr. Jay Hoying is developing a means of replacing damaged capillaries
That’s a problem Dr. Jay Hoying is working to fix with a research project he leads that addresses damaged capillaries, the tiniest of blood vessels. In some cases ... which are arranged in networks, or beds, and supply specific organs and tissues.
Scientists build blood vessels large and small
CAMBRIDGE — Using techniques from the semiconductor industry, a trellis for human cells, and even cotton candy ... wafers with the intricate blood vessel networks. Researchers use the chips as molds to imprint the capillary networks on plastic sheets ...
Brain syncs blood flow to match activities
Arterioles dive into the cortex to feed capillary beds weaving amongst active brain ... Our new finding seems to really connect the dots." Understanding how and why the brain regulates its blood flow could provide important clues to understanding early ...
Biomechanical regulation of blood vessel growth during tissue vascularization
These mechanical forces pulled vessels from the preexisting vascular bed as vascular loops with functional circulation ... implanted on the CAM through elongation of the preexisting capillary network. We studied expansion of the neovasculature after ...
