In an article published in The Journal of the American Medical Association, researchers warned that "patients and physicians should remain cautious about extrapolating the finding of prominent animal research to the care of human disease ... poor replication of even high-quality animal studies should be expected by those who conduct clinical research."
Diseases that are artificially induced in animals in a laboratory are never identical to those that occur naturally in human beings. And because animal species differ from one another biologically in many significant ways, it becomes even more unlikely that animal experiments will yield results that will be correctly interpreted and applied to the human condition in a meaningful way.
