Louis Rosner, Neurology, answeredA very conservative online site to consult is Quackwatch at www.quackwatch.org. Dr. Stephen Barrett recently published a research project on "the shady side of embryonic stem-cell therapy" in which he reviewed five prominent clinics around the world offering stem-cell therapy, although not the one we addressed in Costa Rica. He concluded, "Although stem cell therapy has a few practical applications and considerable promise, there is no reason to believe [they] are providing it as a legitimate service. Their theories and methods are simplistic; their treatments may have adverse effects; they offer no credible outcome data; and their promisies go far beyond what is now possible." What's more, he found at least one clinic refused to detail methods for screening against AIDS or hepatitis.
