Restore heart tissue with stranger's stem cells

US scientists say that stem cells from strangers can be used to restore heart tissue to patients after the pain is very safe and effective as the patient's own cells. The results have been discussed at the American Heart Association in California on November 5.

The study was conducted on 30 patients in Miami and Baltimore. All of them suffer from heart failure due to pain that causes cell damage and scarring. Scar tissue reduces the function of the heart and causes poor blood flow.

In the study, scientists at the University of Miami used bone marrow stem cells, the type of cell believed to be eliminated by the recipient's body while other cell types lacked an important characteristic. The surface will be attacked by the immune system.

15 patients were treated with their own bone marrow cells and the remaining 15 were treated with other people's cells. Results after one year, scar tissue of 30 patients reduced to 1/3 and no difference between the two groups of patients.

'The most important thing of the study is that it is possible to use the cells of a complete stranger, without the need for the same blood type or tissue to treat a patient,' said Dr. Joshua Hare, who led the study. . 'Now stem cells should be available in blood banks so that when needed, they can be immediately provided to patients.'

Cell storage will not cost much more than the cells a person can use to treat many people.
