Durable conduits made by living cells might boost options for dialysis, heart bypass patients
Using human cells as tiny factories, researchers can grow new blood vessels that might someday provide a valuable option for patients undergoing surgery for kidney dialysis or a heart bypass. The new study testing the bioengineered vessels in baboons and dogs raises the prospect of mass-producing such natural-tissue vessels, researchers report in the Feb. 2 Science Translational Medicine.
In coronary bypass surgery, a vein is typically stripped out of a part of the body that can manage without it and implanted on the heart as a conduit supplying blood to the heart muscle. But in some patients, vessels are inaccessible due to obe
