New molecular-level understanding of the brain's recovery after stroke

A specific MicroRNA, a short set of RNA (ribonuclease) sequences, naturally packaged into minute (50 nanometers) lipid containers called exosomes, are released by stem cells after a stroke and contribute to better neurological recovery according to a new animal study. The research provides fundamental new insight into how stem cells affect injured tissue and also offers hope for developing novel treatments for stroke and neurological diseases, the leading cause of long-term disability in adult humans.
