These early tests with stem cells show that severe spinal cord injuries in lab rats can be fixed.
Genetically engineered stem cells can help ratsÃƒÂ¢Ã¢â€šÂ¬Ã¢â€žÂ¢ severed spinal cords grow back together, according to a study published Tuesday.
Rats given the treatment, using stem cells taken from rat embryos, could move their legs again after their spines were severed in the lab, said the researchersÃƒÂ¢Ã¢â€šÂ¬Ã¢â€žÂ¢ report in the Journal of Neuroscience.
The scientists hope the approach, which generated a new fatty cover for the spinal cord cells called the myelin sheath, also could be shown to work in people.
Perhaps Bill Frist made a good move last week?
