Artificial Human Embryos Are Coming, and No One Knows How to Handle Them

Antonio Regalado
MIT Tech Review
September 19, 2017

Here is an excerpt:

Scientists at Michigan now have plans to manufacture embryoids by the hundreds. These could be used to screen drugs to see which cause birth defects, find others to increase the chance of pregnancy, or to create starting material for lab-generated organs. But ethical and political quarrels may not be far behind. “This is a hot new frontier in both science and bioethics. And it seems likely to remain contested for the coming years,” says Jonathan Kimmelman, a member of the bioethics unit at McGill University, in Montreal, and a leader of an international organization of stem-cell scientists.

What’s really growing in the dish? There no easy answer to that. In fact, no one is even sure what to call these new entities. In March, a team from Harvard University offered the catch-all “synthetic human entities with embryo-like features,” or SHEEFS, in a paper cautioning that “many new varieties” are on the horizon, including realistic mini-brains.

Shao, who is continuing his training at MIT, dug into the ethics question and came to his own conclusions. “Very early on in our research we started to pay attention to why are we doing this? Is it really necessary? We decided yes, we are trying to grow a structure similar to part of the human early embryo that is hard otherwise to study,” says Shao. “But we are not going to generate a complete human embryo. I can’t just consider my feelings. I have to think about society.”

Bioethics and multiculturalism: nuancing the discussion

Chris Durante
Journal of Medical Ethics 
Published Online First: 11 August 2017

Abstract

In his recent analysis of multiculturalism, Tom Beauchamp has argued that those who implement multicultural reasoning in their arguments against common morality theories, such as his own, have failed to understand that multiculturalism is neither a form of moral pluralism nor ethical relativism but is rather a universalistic moral theory in its own right. Beauchamp’s position is indeed on the right track in that multiculturalists do not consider themselves ethical relativists. Yet, Beauchamp tends to miss the mark when he argues that multiculturalism is in effect a school of thought that endorses a form of moral universalism that is akin to his own vision of a common morality. As a supporter of multiculturalism, I would like to discuss some aspects of Beauchamp’s comments on multiculturalism and clarify what a multicultural account of public bioethics might look like. Ultimately, multiculturalism is purported as a means of managing diversity in the public arena and should not be thought of as endorsing either a version of moral relativism or a universal morality. By simultaneously refraining from the promotion of a comprehensive common moral system while it attempts to avoid a collapse into relativism, multiculturalism can serve as the ethico-political framework in which diverse moralities can be managed and in which opportunities for ethical dialogue, debate and deliberation on the prospects of common bioethical norms are made possible.

Ethical Guidelines on Lab-Grown Embryos Beg for Revamping

Karen Weintraub
Scientific American
Originally posted on March 21, 2017

For nearly 40 years scientists have observed their self-imposed ban on doing research on human embryos in the lab beyond the first two weeks after fertilization. Their initial reasoning was somewhat arbitrary: 14 days is when a band of cells known as a primitive streak, which will ultimately give rise to adult tissues, forms in an embryo. It is also roughly the last time a human embryo can divide and create more than one person, and a few days before the nervous system begins to develop. But the so-called 14-day rule has held up all this time partly because scientists could not get an embryo to grow that long outside its mother's body.

Researchers in the U.K. and U.S. recently succeeded for the first time in growing embryos in the lab for nearly two weeks before terminating them, showing that the so-called 14-day rule is no longer a scientific limitation—although it remains a cultural one. Now, a group of Harvard University scientists has published a paper arguing that it is time to reconsider the 14-day rule because of advances in synthetic biology.

The U.S. has no law against growing embryos beyond two weeks—as long as the research is not funded with federal dollars. But most scientific journals will not publish studies that violate the 14-day rule, and the International Society for Stem Cell Research requires its members to agree to the rule in order to qualify for membership.

First human-pig 'chimera' created in milestone study

Scientists have created a human-pig hybrid in a milestone study that raises the prospect of being able to grow human organs inside animals for use in transplants.

It marks the first time that embryos combining two large, distantly-related species have been produced. The creation of this so-called chimera – named after the cross-species beast of Greek mythology – has been hailed as a significant first step towards generating human hearts, livers and kidneys from scratch.

Juan Carlos Izpisua Belmonte, who led the work on the part-pig, part-human embryos at the Salk Institute for Biological Studies in La Jolla, California, said: “The ultimate goal is to grow functional and transplantable tissue or organs, but we are far away from that. This is an important first step.”

The study has reignited ethical concerns that have threatened to overshadow the field’s clinical promise. The work inevitably raises the spectre of intelligent animals with humanised brains and also the potential for bizarre hybrid creatures to be accidentally released into the wild. The US National Institutes of Health (NIH) placed a moratorium on funding for the controversial experiments last year while these risks were considered.

New fertility procedure may lead to 'embryo farming', warn researchers

Ian Sample
The Guardian
Originally posted January 11, 2017

A new lab procedure that could allow fertility clinics to make sperm and eggs from people’s skin may lead to “embryo farming” on a massive scale and drive parents to have only “ideal” future children, researchers warn.

Legal and medical specialists in the US say that while the procedure – known as in vitro gametogenesis (IVG) – has only been demonstrated in mice so far, the field is progressing so fast that the dramatic impact it could have on society must be planned for now.

“We try not to take a position on these issues except to point out that before too long we may well be facing them, and we might do well to start the conversation now,” said Eli Adashi, professor of medical science at Brown University in Rhode Island.

The creation of sperm and eggs from other tissues has become possible through a flurry of recent advances in which scientists have learned first to reprogram adult cells into a younger, more versatile state, and then to grow them into functioning sex cells. In October, scientists in Japan announced for the first time the birth of baby mice from eggs made with their parent’s skin.

Should the 14-day limit on embryo research be extended?

by Philip Ball
Prospect Magazine
Originally published December 12, 2016

Here is an excerpt:

That limit has remained in place ever since. But now some scientists believe it should be extended to 28 days. These proposals were discussed on 7th December at a meeting in London organised by charity the Progress Educational Trust. It marked the beginning of what seems likely to be a broad and extended discussion among scientists, bioethicists, fertility specialists, religious leaders and others who have a stake in the moral, legal and scientific status of the human embryo.

(cut)

So the 14-day embryo has begun the process that leads to the laying down of the human body plan—but only just. A key stage, called gastrulation, begins around day 16: this is when the embryo acquires a three-layered structure, the precursor to the appearance of different body-tissue types. So the time between day 14 and day 28 sees the embryo progress through some crucial stages of development, and understanding the details of what goes on, such as the genetic changes involved, should provide a wealth of information that might offer insights into human health, disease and malformation. Much of what we know about these stages at present comes from studies of mice—but as several of the speakers acknowledged, there are some important differences between mice and men.

This is why it looks so enticing for cell biologists and geneticists to investigate the post-14-day embryo. But should that be allowed by a change in the law?

Reframing Research Ethics: Towards a Professional Ethics for the Social Sciences

Nathan Emmerich
Sociological Research Online, 21 (4), 7
DOI: 10.5153/sro.4127

Abstract

This article is premised on the idea that were we able to articulate a positive vision of the social scientist's professional ethics, this would enable us to reframe social science research ethics as something internal to the profession. As such, rather than suffering under the imperialism of a research ethics constructed for the purposes of governing biomedical research, social scientists might argue for ethical self-regulation with greater force. I seek to provide the requisite basis for such an 'ethics' by, first, suggesting that the conditions which gave rise to biomedical research ethics are not replicated within the social sciences. Second, I argue that social science research can be considered as the moral equivalent of the 'true professions.' Not only does it have an ultimate end, but it is one that is – or, at least, should be – shared by the state and society as a whole. I then present a reading of confidentiality as a methodological – and not simply ethical – aspect of research, one that offers further support for the view that social scientists should attend to their professional ethics and the internal standards of their disciplines, rather than the contemporary discourse of research ethics that is rooted in the bioethical literature. Finally, and by way of a conclusion, I consider the consequences of the idea that social scientists should adopt a professional ethics and propose that the Clinical Ethics Committee might provide an alternative model for the governance of social science research.

Genome Editing: An Ethical Review

Nuffield Council on Bioethics
Published September 2016

This review considers the impact of recent advances in genome editing, which have diffused rapidly across many fields of biological research, and the range of ethical questions to which they give rise. It was carried out by an interdisciplinary Working Group that included expertise in science, law, philosophy, ethics, sociology and industry. In coming to its conclusions, the Working Group invited contributions from a wide range of people, including through an open call for evidence that ran from November 2015 until February 2016.

The review sets out our preliminary findings on the impact of genome editing across different areas of biological research and applications, and the range of questions to which this gives rise.

Read on:

  • Genome editing in brief: what, why and how?
  • The context of genome editing
  • Moral perspectives
  • Human health
  • Food
  • Wildlife and ecosystems
  • Other applications: industrial, military and amateur use
  • Conclusions

The next stages of this programme of work will focus on examining and addressing the ethical and practical questions arising in two contexts where genome editing may have a significant impact: firstly, the avoidance of genetic disease and, secondly, livestock farming. Reports on each of these two areas, with recommendations for policy and practice, will be published in 2017.

Driven to extinction? The ethics of eradicating mosquitoes with gene-drive technologies

Jonathan Pugh
J Med Ethics 2016;42:578-581

Abstract

Mosquito-borne diseases represent a significant global disease burden, and recent outbreaks of such diseases have led to calls to reduce mosquito populations. Furthermore, advances in ‘gene-drive’ technology have raised the prospect of eradicating certain species of mosquito via genetic modification. This technology has attracted a great deal of media attention, and the idea of using gene-drive technology to eradicate mosquitoes has been met with criticism in the public domain. In this paper, I shall dispel two moral objections that have been raised in the public domain against the use of gene-drive technologies to eradicate mosquitoes. The first objection invokes the concept of the ‘sanctity of life’ in order to claim that we should not drive an animal to extinction. In response, I follow Peter Singer in raising doubts about general appeals to the sanctity of life, and argue that neither individual mosquitoes nor mosquitoes species considered holistically are appropriately described as bearing a significant degree of moral status. The second objection claims that seeking to eradicate mosquitoes amounts to displaying unacceptable degrees of hubris. Although I argue that this objection also fails, I conclude by claiming that it raises the important point that we need to acquire more empirical data about, inter alia, the likely effects of mosquito eradication on the ecosystem, and the likelihood of gene-drive technology successfully eradicating the intended mosquito species, in order to adequately inform our moral analysis of gene-drive technologies in this context.

Adding ages: The fight to cheat death is hotting up

The Economist
Originally published August 13, 2016

Here is an excerpt:

Scientists at the Institute for Ageing Research at the Albert Einstein College of Medicine, in New York, want to mount a trial of metformin in elderly subjects to see whether it delays various maladies (and also death). If that turns out to be the case, it will go a long way to showing that there is a generalised ageing process that can be modulated with drugs. Nir Barzilai, one of the researchers involved, says an important reason to do the trial is to have an indication against which next-generation ageing drugs can be assessed by regulators.

This sort of interest seems to be triggering a change of tone at America’s Food and Drug Administration over whether it might approve an anti-ageing drug. The regulator is thinking about when a broad, and so far unprecedented, claim of anti-ageing might be considered to be supported by the evidence; it is “looking forward to seeing this area of science evolve”. In the dry language of a government agency these are encouraging words.

If an unregulated diet can do the trick, why does the world need drugs? Three reasons. One is that taking a few pills a day will be easier for most than subsisting on low-calorie muffins and salad. A second is that companies can make money making pills and will compete to create them. A third is that pills may work better than diets. Dr Barzilai, who is in the pill camp, points out that CR works less well in primates than other mammals, and that people with low body-mass indices, a natural condition for those restricting their calories, are in general more likely to die. Those who do well on CR, he says, are likely to be a subset benefiting from the right genetic make-up. His hope is that a range of targeted therapies might allow everyone to get the benefits.

The Epistemology of Cognitive Enhancement

J. Adam Carter & Duncan Pritchard
Forthcoming in The Journal of Medicine and Philosophy

Abstract

A common epistemological assumption in contemporary bioethics held by both proponents and critics of non-traditional forms of cognitive enhancement is that cognitive enhancement aims at the facilitation of the accumulation of human knowledge.  This paper does three central things. First, drawing from recent work in epistemology, a rival account of cognitive enhancement, framed in terms of the notion of cognitive achievement  rather than knowledge, is proposed. Second, we outline and respond to an axiological objection to our proposal that draws from recent work by Leon Kass (2004), Michael Sandel (2009), and John Harris (2011) to the effect that ‘enhanced’ cognitive achievements are (by effectively removing obstacles to success) not worthy of pursuit, or are otherwise ‘trivial’.  Third, we show how the cognitive achievement account of cognitive enhancement proposed here fits snugly with recent active externalist approaches (e.g., extended cognition) in the philosophy of mind and cognitive science.

Gender, identity, and bioethics

Elizabeth A. Dietz
The Hastings Center Report
First published: 15 July 2016

Abstract

Transgender people and issues have come to the forefront of public consciousness over the last year. Caitlyn Jenner' very public transition, heightened media coverage of the murders of transgender women of color, and the panicked passage of North Carolina's “bathroom bill” (House Bill 2), mean that conversations about transgender health and well-being are no longer happening only within small communities. The idea that transgender issues are bioethical issues is not new, but I think that increased public awareness of transgender people and the ways that their health is affected by systems that bioethics already engages with offers an opportunity for scholarship that works to improve transgender health in meaningful ways.

First CRISPR trial in humans is reported to start August 2016

By Sharon Begley @sxbegle
Stat News
Originally published July 21, 2016

Scientists in China plan to use the genome-editing technology CRISPR-Cas9 in patients as early as next month, Nature reported on Thursday. If they go ahead, it would be the first time people would be injected with cells whose DNA has been altered by CRISPR.

A US proposal to run a similar study received approval by a federal ethics and safety panel last month, but it faces months of additional regulatory hurdles before it can go ahead by the end of 2016 at the earliest. The Chinese scientists, led by oncologist Lu You of Sichuan University’s West China Hospital in Chengdu, received approval from the hospital’s review board on July 6, Nature reported, and plan to treat their first patient in August.

Both the US and Chinese scientists would use CRISPR to edit immune-system T cells in patients with cancer in an effort to make those cells destroy malignant cells.

Reason, Emotion, and Implanted Devices

by John D. Lantos
Bioethics.net
Originally published July 13, 2016

Pullman and Hodgkinson present a case that, it seems, should have been an easy one. A competent adult makes a simple request to discontinue a medical therapy. Further, it was a therapy that he’d already tried so personal experience informed his preference to discontinue therapy. His request was repeated over time. He was determined to have adequate decisional capacity. So why did both the physicians and the bioethicists consider this to be a difficult case?

There are certain cases that lead to such dilemmas. They are cases in which emotions tug us in one direction and reason tugs in another. The best example of this type of situation is the difference between withholding a treatment and withdrawing the same treatment. Bioethical principles suggest that these two actions are ethically equivalent. Legal precedent shows that the law treats them as comparable actions. Yet both health professionals and families say that the two actions feel very different. Another example is the difference between withdrawing life-support in a patient who is awake and alert compared to withdrawing life-support in a patient who is unconscious. If the diagnosis and prognosis are the same, then the fact of consciousness does not change the legality or morality of the action. But they feel very different.

Fear and Loathing in Bioethics

Carl Elliott
Narrative Inquiry in Bioethics
Volume 6.1 (2016) 43–46

Abstract

As bioethicists have become medical insiders, they have had to struggle with a conflict between what their superiors expect of them and the demands of their conscience. Often they simply resign themselves to the conflict and work quietly within the system. But the machinery of the medical–industrial complex grinds up conscientious people because those people can see no remedies for injustice apart from the bureaucratic procedures prescribed by the machine itself. The answer to injustice is not a memorandum of understanding or a new strategic plan, but rather public resistance and solidarity.

Federal panel approves first test of CRISPR editing in humans

By Laurie McGinley
The Washington Post
Originally posted on June 21, 2016

A National Institutes of Health advisory panel on Tuesday approved the first human use of the gene-editing technology CRISPR, for a study designed to target three types of cancer and funded by tech billionaire Sean Parker’s new cancer institute.

The experiment, proposed by researchers at the University of Pennsylvania, would use CRISPR-Cas9 technology to modify patients’ own T cells to make them more effective in attacking melanoma, multiple myeloma and sarcoma.

The federal Recombinant DNA Advisory Committee approved the Penn proposal unanimously, with one member abstaining. The experiment still must be approved by the Food and Drug Administration, which regulates clinical trials.

Why Bioethics Needs a Disability Moral Psychology

Joseph A. Stramondo
Hastings Center Report
Volume 46, Issue 3, pages 22–30, May/June 2016

Abstract

The deeply entrenched, sometimes heated conflict between the disability movement and the profession of bioethics is well known and well documented. Critiques of prenatal diagnosis and selective abortion are probably the most salient and most sophisticated of disability studies scholars’ engagements with bioethics, but there are many other topics over which disability activists and scholars have encountered the field of bioethics in an adversarial way, including health care rationing, growth-attenuation interventions, assisted reproduction technology, and physician-assisted suicide.


The tension between the analyses of the disabilities studies scholars and mainstream bioethics is not merely a conflict between two insular political groups, however; it is, rather, also an encounter between those who have experienced disability and those who have not. This paper explores that idea. I maintain that it is a mistake to think of this conflict as arising just from a difference in ideology or political commitments because it represents a much deeper difference—one rooted in variations in how human beings perceive and reason about moral problems. These are what I will refer to as variations of moral psychology. The lived experiences of disability produce variations in moral psychology that are at the heart of the moral conflict between the disability movement and mainstream bioethics. I will illustrate this point by exploring how the disability movement and mainstream bioethics come into conflict when perceiving and analyzing the moral problem of physician-assisted suicide via the lens of the principle of respect for autonomy. To reconcile its contemporary and historical conflict with the disability movement, the field of bioethics must engage with and fully consider the two groups’ differences in moral perception and reasoning, not just the explicit moral and political arguments of the disability movement.

It’s time society discussed the ethical issues raised by the gene revolution

Linda Geddes
The Guardian
Originally posted June 11, 2016

Here is an excerpt:

Since the method was first published in 2012, CRISPR has swept through the scientific community. On Wednesday, the US National Academy of Sciences published a report on the transformative potential of one such application: genetic engineering technology called gene drive. Mosquitoes are currently being engineered with “gene drives” that could render female offspring sterile and potentially wipe species of mosquitoes off the planet .

The technology could also be used to eliminate invasive species such as Japanese knotweed or to reverse herbicide resistance and make agriculture more productive. Until now, such efforts have been stymied because in changing an organism’s DNA, you are reducing its ability to survive and reproduce, meaning the changes are eventually weeded out by natural selection. Gene drives overcome this by ensuring the changes are passed to all offspring. The technology could irreversibly alter entire ecosystems. Another potential application of CRISPR is growing human organs in pigs to meet the demand from transplant recipients. Already, genetically altered pig embryos have been injected with human cells, which it is hoped will develop into pancreases that could be transplanted into humans without the risk of rejection by the immune system.

Dignity, Politics, and Medical Assistance in Dying

by Harry Critchley
Impact Ethics
Originally published June 6, 2016

Here is an excerpt:

A common problem with both of these approaches to understanding dignity, however, is the underlying assumption that dignity is best understood from a theoretical perspective. Another, more fruitful approach might be to examine the meaning of dignity with reference to its use in public discourse. On this view, to determine what dignity is requires that we ask what appeals to dignity are intended to do. Dignity is not only, or even primarily, appealed to in the solitude of philosophical contemplation, but rather in the company of others. Regardless of whether we understand dignity as sanctity of life or as autonomy, its emergence and acknowledgement in the political arena is an achievement not wholly dependent on its theoretical grounding.
