A new era in the ethics of human embryonic stem cell research.

Scientific progress in human embryonic stem cell (hESC) research and increased funding make it imperative to look ahead to the ethical issues generated by the expected use of hESCs for transplantation. Several issues should be addressed now, even though phase I clinical trials of hESC transplantation are still in the future. To minimize the risk of hESC transplantation, donors of materials used to derive hESC lines will need to be recontacted to update their medical history and screening.

Informed consent in human oocyte, embryo, and embryonic stem cell research.

Research with human oocytes, embryos, and additional embryonic stem cell lines is needed to address important scientific questions and to fulfill the promise of stem cell transplantation for degenerative diseases. Proponents need to develop guidelines for the appropriate conduct of embryonic stem cell research. Such guidelines will help build public trust and acceptance for this research.

Medicine. Consent from donors for embryo and stem cell research.

As research with human embryos and embryonic stem cells proceeds, the authors of this Policy Forum argue that all donors of biological materials should give informed consent, including oocyte and sperm donors. Informed consent is particularly important because of the diverse opinions and strong emotions that surround such research. Some gamete donors who are willing to help women and couples bear children may object to the use of their genetic materials for certain types of research.

Ethical review of research involving human subjects: when and why is IRB review necessary?

Requirements for ethical review of research involving human subjects are based on widely accepted international standards that are implemented by various national regulations and institutional policies. In the United States, most human research is reviewed by institutional review boards (IRBs) applying federal standards. Researchers may not realize the variety of studies that should be submitted for review.
