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 ...
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.
Brain power: New insight into how the brain regulates its blood flow
Our new finding seems to really connect ... of the brain's cortex is organized with large arteries and veins on its surface. Arterioles dive into the cortex to feed capillary beds weaving amongst active brain cells. Ascending venules bring blood from ...
In Natural Networks, Strength in Loops
By studying such systems, Magnasco hopes to uncover the reason for the size of the veins, the angles at which they connect ... capillary system had little effect on the larger network — blood simply rerouted itself. However, blocking a penetrating vessel ...
