Ethical question. As we create new discoveries we enter uncharted scientific possibilities where no ethics law has gone. How do we approach regulating these possibilities and their ethical implications while still advancing science? It seems we are on the edge of opening a Pandora's box that could potentially have both miraculously humane and ethically concerning experimental results. Curious about others thoughts.
It ought to be interesting. The article suggests that the problem researchers had to overcome was a timing issue. The proper time during the pig's gestation period for the insertion of human cells into pig's embryo, so that the human cells are not killed off.
So far they have done this with 100,000 cells, they don't know if there are other built in restraints, the human body has trillions of cells.
