Researchers report that cortical neurons derived from human induced pluripotent stem cells, when transplanted into rats with brain lesions similar to those resulting from stroke, functionally integrated into brain circuitry and reversed some of the motor function loss associated with the lesion; the results suggest that grafted stem cell-derived neurons might replace dead cells and restore motor function in stroke, according to the authors.
