Bypass breakthrough: blood vessels made from liposuction

Unless the animals are already sick and need this procedure to survive, I am not in favor of such experiments as a substitute for human trials. To enslave an innocent animal for the sole purpose of experimentation for the benefit of humans is an abomination of human ethics. Animal trials are totally unnecessary when there are plenty of alternative techniques available which are less invasive. The research is laudable. Just don't bastardize it with animal misery.
