Peter Jennings :
This week , we've been taking a closer look at a genetic engineering. Tonight, the incredible potential of another new discovery. We've mentioned before that scientists have managed to cultivate stem cells in the lab . Those are the cells wich are basically the building blocks of the body . This week, yet another advance: making stem cells by combining cells from humans and cows . ABC's John Mckenzie explains

Reporter:
The human body is made of more than 100 billions cells, each one playing a very specific role: in the heart anf the lungs and the brain . But one type of primitive cell creates any tissue anywhere in the body . It is called an embryonic stem cells into those basic all-purpose stem cells . It involves the stuff of science fiction : creating embryonic stem cells that are part human, part cow .

Jim Robl, University of Massachusetts :
On cow eggs, we have a lot of information because we've used those in cloning procedures before . They are readily available.

Rporter:
If it works, this approach has huge implication - these hybrid stem cells could be used to replace any of your cells that aren't working right; treating Parkinson's disease, or diabetes or heart disease .

Professor Jim Robl:
The potential in developing approaches to treat disease is absolutely vast .

Reporter:
In theory, it could even be used to grow your own replacement body parts- including the kidney and bladder, lungs and cartilage, and since they'd be your own cells, there wouldn't be the problem of rejection .
According to the research team, in this technique, a scientist took an unfertilized egg from a cow and removed its nucleus ; the command center containing all the cow's genes and DNA . The scientist then took one of his own cells , scraped from the inside of his cheek and fused it with what remainded of that cow's egg. Quickly, the human nucleus began to take control . The result: an embryo that divided and grew, creating a cluster of what appeared to be human embryonic cells.

John McKenzie:
This research is yet to be formally reviewed by other scientists. Those working on the project first wanted to see how comfortable the public would be with these new embryos, with crossing the barrier between humans and other species
