A clinical trial on a patient in Ohio allowed doctors to take stem cells from the patient's bone marrow and then inject them into the heart. Adult stem cells live in every organ in the body and have the ability to create new, healthy cells. Without any treatment, the human heart has a tough time healing.
But with the stem cell treatment, just a year later, the patient's heart is now operating at near normal capacity.
Researchers stress most of the findings in this stem cell study is years away from actual clinical practice.
