GoKawiilStanford scientists grow human-mouse hybrid brains by suppressing rodent brain development
Stanford researchers who previously showed human brain organoids could survive and function inside baby mice have now genetically engineered mice so their own brains don't fully develop, allowing human tissue to fill the gap more extensively. The approach aims to create better models for studying brain injury and development, while forcing the team to set explicit ethical limits on how far the chimeric brain research should go.
