Human Brain Tissue Fills 90% of Mouse Cortex in Stanford Study

Stanford scientists transplanted lab-grown human cortical organoids into mice engineered to lack most of their cerebral cortex. Within three months, the human tissue occupied over 90 percent of the cortical space and formed working connections with the mouse brain and spinal cord. Published in Nature, the model could advance research into autism, epilepsy, schizophrenia and cerebral palsy.
