Getting Adult Stem Cells on The Move May not Significantly Repair Heart
Promising research leads don't always work out.
In a study published online today in Circulation: Journal of the American Heart Association, researchers report that noninvasive injections of the stem cell mobilization factor granulocyte-colony stimulating factor (G-CSF) is no better than placebo at repairing heart muscle damaged by a heart attack.
The study was also presented today in a featured oral clinical trial presentation at the American College of Cardiology's Scientific Sessions meeting in Atlanta.
Based on earlier animal and human research, researchers hypothesized that G-CSF would increase the release of adult stem cells from the bone marrow into the bloodstream.
