Blood Vessels Grown From Patient’s Skin

From a snippet of a patient’s skin, researchers have grown blood vessels in a laboratory and then implanted them to restore blood flow around the patient’s damaged arteries and veins.

It is the first time blood vessels created entirely from a patient’s own tissues have been used for this purpose, the researchers report in the current issue of The New England Journal of Medicine.

Cytograft Tissue Engineering of Novato, Calif., made the vessels, in a process that takes six to nine months.

Because they are derived from patients’ own cells, they eliminate the need for antirejection drugs. And because they are devoid of any synthetic materials or a scaffolding, they avoid complications from inflammatory reactions.
