The Working Group on the Criteria for Cell-Based Therapies
A Project of the Program in Cell Engineering, Ethics, and Public Policy (PCEEPP), Johns Hopkins University
Supported by a grant from the Greenwall Foundation
The potential of stem cells and related cell-based therapies to treat disease and injury in humans has generated great excitement in the scientific community as well as among patients and their advocates. At the same time, ethical and political debates about the use of human embryos in medical research have captured the public's attention. There is considerable disagreement about the importance of embryonic sources of stem cells to the advancement of cell science, and there is no agreement as to whether the anticipated benefits justify either the destruction of existing embryos or the creation of embryos for purposes of research.
This debate, however energetic, does not exhaust the moral questions that need to be considered in policymaking about stem cell research. It is essential to engage in serious discussions about the next generation of ethical and policy issues in stem cell research on an ongoing basis, while research advances, rather than to react to scientific developments after they occur.
As an interdisciplinary group comprised of leaders in the fields of stem cell biology, ethics, law, population genetics, and transplantation immunology, supplemented by a core group of scientists and scholars from PCEEPP, we considered the following question - does the transition in stem cell research from the laboratory to first human trials and, ultimately, to human therapies raise any particular ethical and policy issues that are either unique to the stem cell context or of heightened concern? We answered this question by focusing first on considerations of safety and secondly on considerations of justice.
The Working Group met for two plenary sessions, on Sept. 4, 2002, and Jan. 17, 2003. Through the plenary sessions and through a variety of smaller meetings, including one-on-one discussions, the Working Group has engaged in in-depth exploration of relevant topics such as immunologic rejection, human leukocyte antigen (HLA) matching in transplantation, conceptions of race and ethnicity, the feasibility of a stem cell "bank" for therapeutic and/or research use, patents and intellectual property, and justice and access to medical technology, among others. While there is literature on each of these topics, the Working Group is, to our knowledge, the first interdisciplinary, collaborative body to examine these issues in regards to stem cell research and cell-based therapies in the American context. The Working Group has authored two reports, one on safety issues in cell-based intervention trials and the other on justice considerations in stem cell research and therapy. The safety paper is published in the November issue of Fertility and Sterility, and the justice paper will appear in the November/December issue of The Hastings Center Report.
