Transplanting mouse stem cells from fatty tissue to the same mouse can reduce damage from a heart attack, researchers at the University of Oslo discovered.
During a study, stem cells were transplanted into the neck of the mice. After some time the researchers induced a heart attack in the mice in a controlled environment, subsequently testing heart function after the heart attack. The same procedure was followed with a control group of ordinary mice.
The hearts of the mice with stem cells showed improved function after the heart attack compared with the control group.
Researchers also transplanted stem cells into mice after inducing a heart attack. These mice also experienced improved heart function to a certain degree. The amount of blood pumped out of the heart in the course of a minute was higher in the mice with transplanted stem cells.
