"Instead of using human eggs, the researchers will remove the nuclei from cows' eggs and replace them with cells from the patients to create cloned stem cell lines that contain the same genetic mutation that results in these neurological disorders."

Essentially what they are doing is taking the motherboard out of one buggy computer and putting it in another, so that they can compare it to a normal working one.

Should this chimera survive and grow up, it would be human, because the directions for making the organism came from human DNA. Only the mitochondrial DNA (outside the nucleus, and not removed and replaced with human) from the original cow egg would be bovine. The original human DNA comes from an adult living person with a known genetic defect. By doing this, we (scientists) can study what is different between a 'normal' and a diseased organism. The growing up to an intact functioning human part is of course not going to happen in a culture dish where these are kept. So, freaking out about this is a waste of O2.

PS, I have no problem with this. I think it's cool as hell.
