Some Stanford research profs are working on producing mice that have brains made up of 100% human cells. Fascinating work, but some of the potential ramifications are a wee bit creepy.
There is growing unease over whether human stem cells could migrate to other parts of the animals, creating human sperm or eggs in their reproductive systems. Should two such "chimera mice" mate, it could lead to the nightmarish scenario of a human embryo trapped in a mouse's womb.
