Stem Cell Research Guidelines Updated

By R&D Editors | September 11, 2008

The National Academies released amended guidelines for research involving human embryonic stem cells, revising those that were issued in 2005 and updated in 2007. The Academies originally produced the guidelines to offer a common set of ethical standards for the responsible conduct of research using human stem cells, an area that, due to an absence of comprehensive federal funding, was lacking national standards.

Since their initial release, the guidelines have served effectively as the basis for oversight of this research in the United States, according to a statement from the National Academies. In addition, a standing advisory committee—a joint project between the Academies’ National Research Council and Institute of Medicine—was established to monitor and review scientific advances and determine any need for revisions.

One reason for the 2008 modifications is to provide guidance on the derivation and use of induced pluripotent cells that were first developed last year. Although induced pluripotent stem cells can be derived without using embryos, the ethical and policy concerns related to their potential uses are similar to those pertaining to human embryonic stem cells. For example, issues arising from mixing human and animal cells in a single organism are relevant for stem cells from both embryonic and nonembryonic sources. However, derivation of induced pluripotent stem cells does not require special stem cell expertise and is adequately covered by current Institutional Review Board regulations, the report says.

At this time it is still undetermined which stem cell types will prove the most useful for regenerative medicine, as most likely each will have some utility, noted the committee that wrote the report. Therefore, the need for research with human embryonic stem cells still exists despite the availability of new cell sources.

The amended guidelines also clarify that “direct expenses” for reimbursement to women donating their eggs for use in stem cell research may include costs associated with travel, housing, child care, medical care, health insurance, and actual lost wages. This language extends the 2005 guidelines, which stated that women who undergo hormonal induction to generate eggs specifically for research purposes should be reimbursed only for “direct expenses” incurred as a result of the procedure, although they did not specify which expenses qualified as direct. The committee stressed that reimbursement for lost wages is not a payment for eggs; the intent is to leave all donors neither better off nor worse off financially.

To instill a high level of confidence that institutions and their researchers are conducting stem cell research responsibly, the guidelines recommend that the public be informed about the types of stem cell research under way and how the research conforms to the institution’s established procedures. Moreover, the committee strongly suggested as a good management practice that institutions conducting human embryonic stem cell research carry out periodic audits of their embryonic stem cell research oversight (ESCRO) committees to ensure proper performance and make the findings of the audits available to the public. The audits should document decisions regarding the acceptance of research proposals and verify that cell lines in use were acceptably derived.

Copies of 2008 Amendments to the National Academies’ Guidelines for Human Embryonic Stem Cell Research are available from the National Academies Press.
