Human brain cells implanted into mice

The video discusses a study published in Nature Biotechnology, where scientists from the Salk Institute transferred human brain cells into mice pups. The cells, taken from human fetuses, were made fluorescent green and inserted into the mice's brains. Researchers used plastic windows on the mice's skulls to observe the development of these cells over several months. The study found that in some areas, human brain cells outnumbered the mice's own cells.
