Transplanted human neurons can integrate into the brains of rats and influence their behaviour

Stanford University

By transplanting human organoids into a rodent brain, researchers can manipulate the cells and see how this affects the animal’s behaviour, saysResearchers have previously carried out this type of transplant in adult rats, but Pasca and his colleagues have now transplanted human brain organoids into rats that were just a few days old. By targeting the rats when their brains were still developing, the researchers hoped that the human neurons would be better integrated into the organs.
