Researchers at Sahlgrenska University Hospital in Sweden have been successful in transplanting blood vessels made from three spoons of blood.

Two years ago two patients at the hospital received the blood vessels made from stem cellsin the blood.

Earlier, another patient too was treated using blood vessels made by her stem cells but in that case, the researchers had to drill into the bone marrow to obtain the stem cells.

In the later cases, all they needed was three spoons of the patient's blood and a waiting period of a week.

The children did not have the vein that goes from the gastrointestinal tract to the liver. This was rectified using the new blood vessels, a treatment that holds out promise for people with varicose veins and myocardial infarction.

The method also rules out rejection normally accompanying any foreign body transplant.

Professors Olausson and Sumitran-Holgersson have treated three patients so far. Two of the three patients are still doing well and have veins that are functioning well.

They now hope to be able to grow complete organs to overcome organ shortage from donors.

Use of embryonic stem cells to treat macular dystrophy and degeneration has been proven to be safewith low rejection rates.
