The Belmont Report at 40: Reckoning With Time.

It was the summer of 1972 when a stunned nation first learned of the infamous Tuskegee Syphilis Study, during which hundreds of poor, disease-stricken black men from Macon County Alabama, had been deliberately left untreated for 40 years. Coming on the heels of multiple, earlier examples of unethical human experimentation, the Tuskegee Syphilis Study made it plain that the moral foundation of human subject research was in desperate need of repair. Blind reliance on the Nuremberg Code and the Declaration of Helsinki was no longer going to suffice.

Safety issues in cell-based intervention trials.

We report on the deliberations of an interdisciplinary group of experts in science, law, and philosophy who convened to discuss novel ethical and policy challenges in stem cell research. In this report we discuss the ethical and policy implications of safety concerns in the transition from basic laboratory research to clinical applications of cell-based therapies derived from stem cells. Although many features of this transition from lab to clinic are common to other therapies, three aspects of stem cell biology pose unique challenges.
