Ethical Issues in Stem Cell Research

The question remains, though, whether this degree of cellular interaction is sufficient to render the early human Stem cell research ethical or not a human being. The main difficulty for those who appeal to such mental capacities as the touchstone for the right to life is that early human infants lack these capacities, and do so to a greater degree than many of the nonhuman animals that most deem it acceptable to kill Marquis The embryo has no moral status at all An embryo is organic material with a status no different from other body parts.

If a pre-embryo is not covered by the Biblical commandment of "thou shall not murder," then we might allow destroying a pre-embryo for its stem cells if it would save the life of an already born person. Using them for scientific research uses a resource that would otherwise be wasted.

Sometimes ethical issues behind scientific advances are not fully addressed until it is too late, as during the development of the first atomic bomb. The answer hinges on how we view the embryo. The results seem clear: Adult stem cells can be isolated through plasmapheresis.

From a therapeutic standpoint, the HESCs obtained from leftover IVF embryos are not genetically diverse enough to address the problem of immune rejection by recipients of stem cell transplants. The embryo has no moral status at all An embryo is organic material with a status no different from other body parts.

The Mishna clearly states that if the life of a woman in labor is threatened by her fetus, the fetus should be aborted. Arguments for this view There are several stages of development that could be given increasing moral status: It forces us to choose between two moral principles: The difference between these types of capacity is said to be a difference between degrees of development along a continuum.

There is thus reason to doubt that there is a moral distinction between creating embryos for research and creating them for reproductive purposes, at least given current fertility clinic practices.

Legislators have had the unique challenge of encouraging advances in science and medicine while preserving a respect for life. There is a cut-off point at 14 days after fertilization Some people argue that a human embryo deserves special protection from around day 14 after fertilization because: President Obama overturned Bush's stem cell policy in to expand the number of stem cell lines available to researchers.

For example, the research could provide important insights into the fundamental processes of gamete biology, assist in the understanding of genetic disorders, and provide otherwise infertile individuals a means of creating genetically related children.

Opponents may feel deep moral unease or repugnance, without articulating their concerns in more specific terms. Each of these enterprises has its own set of ethical issues. First, because of errors during reprogramming of genetic material, cloned animal embryos fail to activate key embryonic genes, and newborn clones misexpress hundreds of genes 37 The duty to prevent or alleviate suffering The duty to respect the value of human life In the case of embryonic stem cell research, it is impossible to respect both moral principles.

There is arguably an important difference between the transplant case and HESC research insofar as the moral wrong associated with the latter a systematically devalues a particular class of human beings and b is largely socially accepted and legally permitted.

Researchers and SCROs need to distinguish core ethical standards that are accepted by international consensus—informed consent and an acceptable balance of benefits and risks—from standards that vary across jurisdictions and cultures.

Would Judaism sanction such a solution? In rebuttal, however, some argue that pluripotent entities created through SCNT are biologically and ethically distinct from embryos It will require years of very expensive, labor-intensive research to determine the potential that stem cells hold for the treatment, palliation, and cure of human illness.

A somatic cell, on the other hand, does not have the inherent capacity or disposition to grow into a mature human being.

However, the creation of embryos for research in this situation would not necessitate the destruction of the embryos, as it does when embryos are created to derive stem cell lines.

If we could clone one of his cells, but instead of allowing the cloned cell to develop into a fetus, we might place it into the appropriate environment that would cause it to differentiate into a liver that would be virtually genetically identical to that of the sick man. Stem Cell Clinical Trials Transplantation of cells derived from pluripotent stem cells offers the promise of effective new treatments.

President Bush, for example, limited federal funding to a study of 70 or so hES cell lines back in If there are conditions under which a researcher may use HESCs without being complicit in the destruction of embryos, then those who oppose the destruction of embryos could support research with HESCs under certain circumstances.

It needs external help to develop. If life begins at conception, as many conservative groups believe, when did life begin for each of these twins?

However, most investigators who conduct research with HESCs obtain them from an existing pool of cell lines and play no role in their derivation.

While hES cells are isolated from an embryo, iPS cells can be made from adult cells. But, the ultimate promise of stem cell technology would be to combine it with cloning.

Ethics of Stem Cell Research

Large-scale genome sequencing will yield insights about the pathogenesis of disease and identify new targets for therapy. Thus there may be a tension between respecting the autonomy of donors and obtaining scientific benefit from research, which can be resolved during the process of obtaining consent for the original donation of materials.

Does life begin at fertilization, in the womb, or at birth?Watch video · Embryonic stem cells offer hope for new therapies, but their use in research has been hotly debated.

Different countries have chosen to regulate embryonic stem cell. Conclusion. The stem cell-research is an example of the, sometimes difficult, cost-benefit analysis in ethics which scientists need to do.

Even though many issues regarding the ethics of stem cell research have now been solved, it serves as a valuable example of ethical cost-benefit analysis.

There are a number of ethical sources of stem cells that hold out realistic hope for cures and treatments of diseases. Stem cells from adult tissues, which are committed to differentiating into a limited number of cell types such as liver, brain or blood, are called adult stem cells.

The Church does not oppose all stem cell research. In. Stem Cell Research: The Ethical Issues provides detailed descriptions of the arguments adopted by proponents of stem cell research. It is a great resource for anyone with a biological background seeking intelligent arguments in support of stem cell research.

Ethics of Stem Cell Research First published Fri Apr 25, ; substantive revision Mon Jan 28, Human embryonic stem cell (HESC) research offers much hope for alleviating the human suffering brought on by the ravages of disease and injury. Apr 14,  · Stem cell research offers great promise for understanding basic mechanisms of human development and differentiation, as well as the hope for new treatments for diseases such as diabetes, spinal cord injury, Parkinson’s disease, and myocardial infarction.
