One of the newest applications of cell technology is called cybrid embryos. This process involves replacing the nuclear material of an animal cell with human nuclear material. How might this process affect public policies about research by using stem cells?

Cybrid embryos contain human nuclear material, so their use in stem-cell research raises many of the same ethical and policy concerns as research involving human embryonic stem cells. The policies would most likely apply in a similar way, rather than treating them as ordinary animal embryos or regular cells solely because they are not entirely human in origin.
