But I think it is quite controversial because, despite the similarities of being living organisms, the response to certain medications will not be the same as that of a human body
that's why after being successful in animals it has a clinical trial, where we test in humans
In fact, testing it on animals will never be reliable. I think the option of using clones is more logical, but it is still controversial.
I would have no problem with them cloning a human artificially created in a laboratory. If stem cells are currently used to cure diseases and replace organs, why not use them for this type of tests?
