Resuspended artificial blood vessels can improve medical care. That's why.

Counterfeit blood vessels begin to get real. New studies have shown that bioengineerous blood vessels are capable of incorporating living cells after implantation into the human body, becoming bloody, self-sustaining tubes that function less as substitutes for human blood vessels and more like real things. 1

9659006] The so-called human noncellular vessels (HAVs) are experimental devices and are not yet ready for wide application. But if new studies are confirmed by further research, HAVs can ever be used to treat medical problems ranging from cardiovascular disease to gunshot wounds.

"This is the wave of the future," said Lola Eniola Adefeso, a University of Michigan professor of biomedical engineering who was not involved in the study described on March 27 in Science Translational Medicine.

For researchers, scientists and biomedical engineers at Yale University and Humacyte, Regenerative Medical Technology in Durham, North Carolina has created HAVs, taking arterial cells from corpses, growing them in new blood vessels, and then removing cells. After treatment, all that was left was the so-called cell matrix – the web of collagen and protein, which gives the vessel its structure.
