Stanford mixes human cells with mouse brains
a team at stanford created mice with nearly half their brain volume replaced with human cells, raising questions about brain injury research and ethics.
a stanford team developed mice with underdeveloped brains, then replaced nearly half of their brain volume with human cells. multiple cameras tracked the mice's movements, and a computer charted their position and speed. this experiment could help scientists study brain injuries and potentially lead to new treatments. however, it also raises questions about the ethics of mixing brain tissues of different species. the research may have implications for understanding brain function and development.
