Stanford Transplants Lab-Grown Human Brain Tissue into Mice
The grafts grew for months, formed functional connections and produced human cell types not normally found in mice, researchers said.
- On Wednesday, Stanford University neuroscientists published a study in Nature describing a new method for growing human brain organoids inside genetically engineered mice.
- Previous attempts failed because rodent cells outcompeted human grafts; neuroscientist Sergiu Pașca and his Stanford University team solved this by engineering mice lacking specific cerebral cortex and hippocampus structures.
- In 25 of 29 attempts, human tissue filled more than 90% of the vacant space, forming specialized neurons including rare von Economo cells never before grown in a dish.
- These chimeric animals provide a platform to study cerebral palsy and frontotemporal dementia; Pașca noted human cortical cells appear to restore lost functions in the grafted mice.
- Experts like Nita Farahany of Duke Law emphasize ethical caution as the team deliberately halted experiments before human cells formed consciousness markers, noting this work "brings us into new gray areas.

A team from Stanford University, led by the Romanian Sergiu Pasca, managed to transplant human brain cells into the brains of mice. The study published in Nature magazine shows that this opens the way to research into how serious diseases such as schizophrenia, epilepsy or cerebral palsy occur, transmits Stanford University. The team coordinated by Sergiu Pasca ...
Researchers transplanted human brain organs to animals to study schizophrenia, epilepsy, DTC, dementia, and other neurological disorders.
Map of the estimated pathways of nerve fibers in the brain of a S. Pasca lab rat, Stanford Universit A group of American scientists achieved something that, until recently, seemed to belong to the script of a science fiction film: creating live mice in which much of the brain is formed by human neurons. Animals can walk, eat, explore the environment and perform tasks like other mice. And this detail is important: they continue to behave essentia…
Human brain cells have been transplanted into mice and they are observing how disease processes are expressed in human brain tissue.
