Stem Cell Therapy for Stroke Shows Need for Rigorous Trials in US

June 23, 2015

(Medical Xpress) – The news that legendary Green Bay Packer quarterback Bart Starr has undergone stem cell therapy to recover from a stroke has raised the profile for a promising but unproven regenerative treatment intended to replace dead neurons with live ones.The University of Wisconsin-Madison’s Su-Chun Zhang was the first scientist to isolate neural stem cells from embryonic stem cells and then from other types of all-purpose stem cells. He says medical researchers and the federal government have a responsibility to forge ahead with clinical trials to prove whether and how these flexible cells can replace damaged or dead neural cells caused by spinal cord injury, stroke and Lou Gehrig’s disease (ALS).
