Human brain tissue grown in mice for first time

Scientists have successfully grown human brain tissue inside mice for the first time using a new genetic engineering technique. By transplanting lab-grown human brain cells into rodents engineered without a cortex or hippocampus, researchers created space for the tissue to develop. This breakthrough aims to aid the quest for treatments for incurable neurological conditions, providing critical insights into disorders such as schizophrenia, epilepsy, cerebral palsy, intellectual disability, and rare forms of dementia to improve patient outcomes.
