Toronto: A new discovery that tricks aging stem cells into rejuvenating mode could enable scientists to create youthful patches for damaged or diseased hearts and heal them, according to a Canadian study.The breakthrough may enable scientists to create such life giving patches from a patient`s own stem cells - regardless of the patient`s age - while avoiding the threat of rejection, the study claims.“Stem cell therapies involving donated bone marrow stem cells run the risk of patient rejection in a portion of the population,” argues Milica Radisic, associate professor of chemical engineering and applied chemistry at the University of Toronto, the Journal of the American College of Cardiology reports.One method of avoiding such a risk has been to use cells derived from a patient`s own body. But until now, clinical trials of this kind of therapy using elderly patients` own cells have not been a viable option, since aged cells tend not to function as well as cells from young patients, according to a Toronto statement.
