Human / Mouse Hybrid: Glial Cell Transplants

Human / Mouse Hybrid: Glial Transplants Nero-scientists injected some human glial cells into the brains of newborn mice. The mice grew up, and so did the human glial cells. The cells spread through the mouse brain, integrating perfectly with mouse neurons and, in some areas, outnumbering their mouse counterparts. The researchers say these mice are measurably smarter.
