Discussion 5: Stem Cell Research and Ethical Considerations in Policy

Standing in the voting booth, Raina hesitated. It was November 2, 2004, and she had to make her final decision on how to vote for California Proposition 71, the California Stem Cell Research and Cures Initiative. Proposition 71, a $3 billion bond measure, would fund embryonic stem (ES) cell research at facilities across the state for the next ten years. Raina knew that Proposition 71 had widespread support, including that of Governor Arnold Schwarzenegger and several Nobel Prize-winning scientists, but she was also well aware of the controversy surrounding ES cell research. Well before Election Day, Raina had taken the time to inform herself about the ongoing ES cell debate.

She learned that ES cell lines are obtained by removing a group of cells, called the inner cell mass, from an embryo that is about five days old (also known as a blastocyst), and growing the cells in a Petri dish. The cells are prized by researchers because they are pluripotent, meaning that they have the potential to differentiate into a wide range of different types of cells if properly stimulated. Proponents of ES cell research say that such cells could be used to cure conditions such as Parkinson’s disease, diabetes, heart disease, Alzheimer’s disease, cystic fibrosis, and spinal cord injuries. In addition, ES cells could be studied to help scientists understand the basic processes of human development and used to test new drugs.

ES cell research opponents say that it should be restricted because it requires the destruction of human life. Raina found this issue to be one of great concern. She learned that the ES cell lines currently used for research are obtained from embryos left over from in vitro fertilization (IVF). These embryos are voluntarily donated, and otherwise would be discarded. Raina wondered if embryos, even those so early in development, should be considered human beings.

If so, then producing an excess of them for IVF and then discarding them would be wrong. Might it also be wrong to benefit from their sacrifice? Raina had read about stem cells from other sources besides embryos. Some, known as embryonic germ cells, may be obtained from aborted or miscarried fetuses, but this source is subject to the same sort of controversy as ES cells. Some very promising results have come from research using stem cells taken from the umbilical cord and placenta, and adult tissues such as bone marrow and parts of the brain.

In fact, some of these non-embryonic cells have already been used to treat medical conditions, including blood disorders, spinal cord injury and heart attack damage. Such stem cells are obtained without harming embryos or fetuses, and for this reason their use meets with few ethical objections. However, they appear to be more limited in their ability to differentiate than ES cells. Finally, after weighing the arguments one last time, Raina cast her ballot. The next day, she learned that Proposition 71 had passed with 59% of the vote.

Now it is possible that similar initiatives may appear on the ballots of other states. Should ES cell research prove fruitful, it raises the issue of a particular type of cloning known as therapeutic cloning. Therapeutic cloning would not result in the production of a new human being, but it would mean creating an embryo from which ES cells could be removed that would match the cells of a person’s own body. This would prevent the rejection of transplanted cells by the immune system of the recipient. Would you support the use of therapeutic cloning in order to produce ES cells for treatment of disease or injury? Why or why not?

Stem cell research, particularly involving embryonic stem (ES) cells, has been a subject of intense ethical, scientific, and political debate. This debate hinges on balancing the potential health benefits against moral concerns about the destruction of human embryos. The ethical considerations revolve around at what stage human life begins, and whether embryos should be granted moral rights equivalent to those of living persons. Scientific advancements have revealed promising avenues for regenerative medicine, but also underscore the ethical complexities associated with manipulating human embryonic life.

Embryonic stem cells are derived from blastocysts, which are approximately five days old, collected from surplus embryos left over from in vitro fertilization procedures. These cells are capable of developing into nearly any cell type in the human body—a property known as pluripotency—making them highly valuable for medical research and potential therapies. Scientific research suggests that ES cells could be instrumental in treating a wide spectrum of diseases, including Parkinson’s disease, diabetes, heart disease, Alzheimer’s disease, cystic fibrosis, and spinal cord injuries. The ability to generate specific cell types from stem cells could revolutionize medicine by enabling replacement of damaged tissues, thereby restoring lost functions and improving patients’ quality of life (Thomson et al., 1998). Moreover, studying embryonic stem cells can deepen our understanding of human development, disease mechanisms, and drug testing (Drukker et al., 2004).

However, opposition to ES cell research primarily emphasizes ethical concerns regarding the destruction of early-stage human life. Critics argue that embryos at the blastocyst stage possess a moral status akin to that of a human being. Consequently, harvesting stem cells involves destroying potential human life, which many believe to be ethically unacceptable (Kass, 2003). Those opposed to embryonic destruction endorse alternative sources of stem cells, such as adult stem cells, umbilical cord blood, and placental stem cells. These sources can be obtained without harming the donor and have already been used in treatments for blood disorders, spinal cord injuries, and cardiac conditions (Lanza et al., 2001). Nonetheless, these non-embryonic stem cells tend to have more limited differentiation potential compared to ES cells, which raises questions about their ultimate utility for certain therapeutic applications (Köhler et al., 2007).

The controversy extends into the realm of biotechnology, specifically concerning therapeutic cloning, a process that involves creating an embryo through somatic cell nuclear transfer that is genetically matched to a donor. This embryo could then provide somatic cells for regenerative therapies without immune rejection. Supporters argue that therapeutic cloning could solve organ shortage problems and facilitate personalized medicine, thus saving numerous lives (Wilmut et al., 2006). Opponents, however, contend that this form of cloning blurs ethical boundaries, as it involves creating and then destroying human embryos, raising fears about potential misuse and the slippery slope toward reproductive cloning (Francis, 2005).

Supporting therapeutic cloning hinges on the potential health benefits and the ethical acceptability of creating embryos solely for medical purposes. Advocates suggest that the embryos created through cloning are no different morally from other early-stage embryos used in research, especially when the goal is to save lives and alleviate suffering (Lo and Parham, 2009). Opponents rebut that cloning commodifies human life and risks devaluing human dignity, emphasizing that it could eventually lead to reproductive cloning, which is widely condemned (De Roubaix et al., 2007). The debate remains unresolved, with many policymakers, scientists, and ethicists calling for responsible regulation to maximize therapeutic benefits while minimizing moral concerns.

In conclusion, embryonic stem cell research and therapeutic cloning represent promising frontiers in regenerative medicine but are fraught with ethical dilemmas rooted in the moral status of the embryo. Advances in alternative stem cell sources have offered some hope for circumventing ethical issues, yet the full potential of ES cells remains unparalleled. As science progresses, society must grapple with the moral implications of manipulating early human life and establishing policies that ethically balance innovation and respect for human dignity.
