New Organs Could Come from Pig Embryos

In a way, I suppose it only makes sense. If we're already using pig arteries in heart valve transplant operations, and openly discussing the use of stem cells to create donor organs, the next logical step is to look at developing New Organs from Pig Embryos.

There are big hurdles, not the least of which is massive rejection by the human body of animal tissue.

Researchers are working to genetically engineer pigs that do not carry the protein responsible for the immune response.

Needless to say, this raises a whole host of ethical questions. The fields of science, medicine and biotechnology are rapidly bending the curve with which rational human response can be developed. It's a whole new world out there.
