Stem cell technology used in unique surgery Featured

For the first time ever in the world, researchers at the Sahlgrenska Academy at the University of Gothenburg, Sweden, have produced a blood vessel from stem cells and then used it in an operation on a 10-year-old girl at the Sahlgrenska University Hospital.

Surgeon and Professor Michael Olausson was able to create a new connection with the aid of this blood vessel between the liver and the intestines. The girl developed during her first year of life a blood clot in the blood vessel that leads blood from the intestines to the liver. This introduced the risk that she would experience life-threatening internal bleeding.

Blood vessels from a dead donor were used in the present case. The vessel was then chemically treated to remove all cells RNA and DNA. This left just the supporting tissue. Stem cells were then obtained from the girl’s bone marrow and these were added to the supporting tissue. A new blood vessel grew in just under four weeks. This was used during the surgery in order to create the new connection between the liver and the intestines.

The next step is to intensify research into the recreation of other organs, and to develop methods that can be used for arteries.
