Stem cells might reverse heart damage from chemo

"Certain types of chemotherapy can damage the heart while thwarting cancer, a dilemma that has vexed scientists for years. But a new study in rats finds that injecting the heart with stem cells can reverse the damage caused by a potent anti-cancer drug. The findings could one day mean that cancer patients could safely take higher doses of a powerful class of chemotherapy drugs and have any resulting damage to their hearts repaired later on using their own cardiac stem cells, the researchers said. The study was published online December 28 in advance of print publication in the journal Circulation" - HealthDay
