Adult stem cells has been compiling more promise for future medical research with no ethical qualms. On the other hand, embryonic stem cell research has no compiling record with major ethical concerns! The breakthrough of science back in 2009, continues to dazzle with more breakthroughs with understanding pluripotent cells (adult stem cells reprogrammed back to their embryonic stage).
New Scientist reports of a discovery with human skin containing important adult stem cells that are able to repair wounds! These cells exist in sweat and are not found in animals, the article adds this…“Humans have three times more eccrine glands than hair follicles, making them the major contributor to new skin cells.” Elaine Fuchs from the Howard Hughes Medical Institute in Maryland says the discovery was unexpected and goes against current dogma!
In Medical Xpress, pluripotent cells could be used to create personalized medicine for cancer patients!
“In the November 19 online early edition of the Proceedings of the National Academy of Sciences (PNAS), they report that these new stem-like cells do not express the same genes as embryonic stem cells and induced pluripotent stem cells (iPSCs) do.”
“That explains why they don’t produce tumors when they grow in the laboratory, as the other stem cells do, and why they are stable, producing the kind of cells researchers want them to. “These seem to be exactly the kind of cells that we need to make regenerative medicine a reality,” says the study’s senior investigator, chairman of the department of pathology at Georgetown Lombardi, a part of Georgetown University Medical Center.”
Very exciting news in adult stem cell research! Are you looking to refresh those old cells of yours? Well guess what? Researchers at the University of Toronto discovered a way to refresh those old cells, making them look young again!
Science Daily reports…
“A new method of growing cardiac tissue is teaching old stem cells new tricks. The discovery, which transforms aged stem cells into cells that function like much younger ones, may one day enable scientists to grow cardiac patches for damaged or diseased hearts from a patient’s own stem cells — no matter what age the patient — while avoiding the threat of rejection.”
With so much success continuing for adult stem cells which has been quite amazing, it seems superfluous to continue work with ethically-charged embryonic stem cells where concerns about abuse are being raised.
Can one trust scientist to regulate themselves with ethics? This is something the public insists upon. However rigging public support is an unethical practice. Here is an example of claiming to employ an unbiased statistical sample of the public concerning stem cell research…
“Representing the Public in Public Engagement: The Case of the 2008 UK Stem Cell Dialogue” where Alison Mohr and Sujatha Raman (PLoS Biology) analyze the situation…
“Efforts to engage the public in science take many forms, yet in many cases, “engagement” is a means toward acceptance rather than true participation. In 2008, the largest ever public engagement (PE) exercise sponsored by UK Research Councils was held. The Stem Cell Dialogue (SCD), designed to identify the range of views and concerns amongst the wider public about stem cell research, was jointly supported by the Biotechnology and Biological Sciences Research Council (BBSRC), the Medical Research Council (MRC), and Sciencewise.”
The SCD revealed high levels of public support for stem cell science and technology, according to the official press release , and thus seems to validate the traditional reasons offered for conducting PE around cutting-edge science: that engaging the wider public in dialogue at an early stage can help scientists communicate the motivations for their research, including its expected societal benefits, assuage potential ethical concerns, avert damaging controversies, and secure public acceptance.”
“But, is this instrumental rationale–engagement toward a predetermined goal–sufficient? Can it offer the democratic legitimacy that underlies the recent turn to this type of “upstream” engagement? And does the SCD as it actually unfolded merit the summary finding of public support reported in the press release? In this paper, we draw from our work as official evaluators of the SCD (see Box 1), and recent debates on the purpose of engagement, to ask: how should we understand the “public” in PE; why is PE important for both society and science; and what lessons should we take from actual PE exercises? “
Some very good questions, the problem is, employing an unbiased statistical sample of the public concerning stem cell research is not the case! Yes, you read about how “competing rationales for representing the public can lead to particular outcomes that conflict with the democratic ideals of PE.” So they take into account opposing viewpoints towards the research. But look who they omitted in the sample…
“The lack of alternative or more critical/skeptical perspectives of counter-experts (e.g., advocacy/pro-life group, religious group, journalistic, or National Health Service viewpoints) limited the range of participants’ discussion and increased the potential for obtaining positively biased indications of public approval and acceptance.”
The workshops contained mostly those who were for the research while skeptical perspectives were practically invisible! What does that mean? It means, a rigged sample of representing the public! By using this method, the public would be portrayed as overwhelmingly supported of any type of research being conducted!
“The homogeneity of responses appears to have been shaped by the role played by experts in framing the discussion. Framing played a significant role in bounding the discussions as participants showed a strong tendency to follow and explore the main issues raised in the experts’ presentations.”
Not only does this rigging of public support happen with stem cell research, but it happens often with evolution which also requires public engagement! Despite the flaw and unethical ways of rigging public opinion, adult stem cell continues to flourish with astounding advancements for promising treatments for various people which would enhance our heath greatly!
