Blood vessels grown from patient's own tissues used successfully in human patients

Thirteen months and so far so good. Unlike earlier techniques used in Japan, which involved growing cells on a scaffold that slowly dissolved after implantation, scientists in Argentina grew whole stretches of blood vessel from the patients' own cells. The patients in question have damaged veins and arteries in their arms from regular dialysis.

This does not involve stem cells of any kind. A strip of skin is removed from the patient, but the fibroblast and endothelial cells are taken from the inside of the veins in that strip of skin
