Stanford Study Implants Human Brain Tissue into Mice to Observe Development

Researchers at Stanford University transplanted human brain organoids into newborn mice with genetically modified, vacant cortical spaces in a process termed xenocortication.

The transplanted human tissue expanded to comprise about 92 percent of the animal's cortical tissue by three months while producing active neural connections.

The study provides a model to observe human brain development and study potential neurological disorders, though researchers noted the tissue remained immature.
