Stem cell research controversy newspaper articles
In this column, I report on findings specific to media coverage, and in a future column I will discuss trends related to public opinion.
The debate about stem cells is also a religious one.
Origins, ethics and embryos: the sources of human embryonic stem cells. No precursors of the extra-embryonic tissues had been generated.
Ideally, terms should reflect the cellular composition and tissue organization of each, and indicate their developmental stage and potential.
Stem cell controversy
For example, one rationale for allowing the use of deidentified materials is that the ethical risks are very low; there can be no breach of confidentiality, which is the main concern in this type of research. As far as we know, this structure arises during the second week, soon after implantation. Obtaining consent for future research with induced pluripotent cells: opportunities and challenges. Framing involves a contest to emphasize certain dimensions of an issue over others, thereby helping to construct meaning. Finally, some people regard repugnance per se an unconvincing guide to ethical judgments. Some people view such hybrid embryos as contrary to a moral order embodied in the natural world and in natural law. Both guidelines and information should be disseminated to journalists, ethics committees, regulatory bodies and policymakers. This creates complex issues , as people have different beliefs about what constitutes the start of human life. Scientists can extract adult stem cells from different types of tissue, including the brain, bone marrow , blood vessels, skeletal muscle, skin, teeth, the gut, the liver, among others. They have incorporated tissues into the models that resemble those that become the yolk sac and placenta. Published December 3, Second, we urge regulators to ban the use of stem-cell-based entities for reproductive purposes. Embryonic Stem Cell Research Pluripotent stem cell lines can be derived from the inner cell mass of the 5- to 7-d-old blastocyst. Confidentiality must be carefully protected in embryo and hESC research because breaches of confidentiality might subject donors to unwanted publicity or even harassment by opponents of hESC research
Shifts in the amount of Congressional testimony specific to the issue reflect the movement of the issue from generally administrative arenas through to the overtly political in There should be a sound scientific justification for using human oocytes and embryos to derive new human stem cell lines.
Today, such iPS cell usage is seen as a new route to research implementing human embryonic stem cells [ 16 ], and a recent survey of 26 hospital patients indicated a generally positive and supportive attitude towards donation of biological material for iPS research [ 17 ].
However, it will not remove the ethical concerns over the use of human ES cells.
Ethical issues of stem cell therapy
Some people, however, believe that an embryo is a person with the same moral status as an adult or a live-born child. However, ethical concerns arise if researchers work with lines that were derived in other jurisdictions under conditions that would not be permitted at their home institution. In the United States, for example, a sizable minority has objected to the fact that five-day-old preimplantation human embryos are destroyed in the process of harvesting their stem cells 2. Such concerns about undue influence, however, may be addressed without banning payment. For these reasons, cloning for reproductive purposes is widely considered morally wrong and is illegal in a number of states. They should send their research proposals to a stem-cell oversight committee or a local independent ethical review board before undertaking any studies, submit their results to peer review and publicize their findings. Here, the key consideration was the intention of the study rather than whether the clone was equivalent to a natural embryo. However, gamete donors who are willing to help women and couples bear children may object to the use of their genetic materials for research. And unless this essential step is taken, the potential of a preimplantation embryo for full human life exists only in the most abstract and hypothetical sense 3. Living in a pluralistic society such as ours, supporters argue, means having to tolerate differences in religious and personal convictions over such personally theoretical matters as when during the course of human biological development moral personhood first appears. Although identifying information about donors must be retained in case of audits by the Food and Drug Administration as part of the approval process for new therapies, concerns about confidentiality may deter some donors from agreeing to be recontacted. However, these lines may not be safe for transplantation into humans, and long-standing lines have been shown to accumulate mutations, including several known to predispose to cancer. National Research Council. While public concerns such as these about science and its implications are not in themselves new, hES cell research offered the opportunity for all of these inchoate worries to coalesce around a single, new scientific field.
It is safe to say that, despite a host of other concerns about where science was leading us in the future, the ethical discourse over stem cell research for the past decade has been characterized predominantly by the debate over embryo destruction.
Published December 3, Thus, logistically it would be possible to carry out embryo and stem cell research on deidentified materials without consent.
