Mayo researchers observe genetic fusion of human, animal cells -may help explain origin of AIDS
...y, Mayo Clinic investigators implanted human blood stem
cells into fetal pigs. The pigs look and behave like normal pigs. But cellular analysis shows they have some human blood cells, as well as some cells that are hybrids -- part human, part pig -- in their blood, and in some of their organs. Molecular e...
