A stem cell therapy previously shown to reduce inflammation in the critical time window after traumatic brain injury also promotes lasting cognitive improvement, according to a pre-clinical study reported in the current issue of STEM CELLS Translational Medicine.
Cellular damage in the brain after traumatic injury can cause severe, ongoing neurological impairment and inflammation. Few pharmaceutical options exist to treat the problem. About half of patients with severe head injuries need surgery to remove or repair ruptured blood vessels or bruised brain tissue.
A stem cell treatment known as Multipotent Adult Progenitor Cell (MAPC®) therapy, has been found to reduce inflammation in rats immediately after traumatic brain injury, but no one had yet gauged its usefulness in promoting recovery of neurological function over time. Now, a group of scientists studying that question has come up with a preliminary answer.
