Based on a general review of international, representative tissue banking policies that were described in the medical, ethics, and legal literature, this paper reviews the range of standards, both conceptually and in existing regulations, relevant to four main factors: (1) commercialization, (2) confidentiality, (3) informed consent, and (4) quality of research. These four factors were selected as reflective of some of the major ethical considerations that arise in the conduct of tissue banking research. The authors emphasize that any policy or ethical guidelines designed to regulate tissue bank research should address all four factors. Whenever this sort of research is conducted between several institutions or several countries, the paper suggests that the relevant entities work collaboratively to harmonize their standards.

Many medical schools' oaths differ in substantive content. The impact of using a nonstandardized medical oath on physicians' professionalism and the inculcation of common ethical values and principles remains unknown.
