Human neurons successfully grown inside mouse brains, Stanford study finds
Mice implanted with human brain cells do better in maze tests, suggesting a possible way to study disorders like cerebral palsy and raising ethical questions
Researchers at Stanford University have implanted lab-grown human cells into the brains of mice, in an experiment that could offer a new way to study brain disorders. According to a study published in Nature, the human tissue, derived from donor stem cells, grew inside the animals’ brains and appeared to improve their performance in cognitive tests.
