In: Science and Engineering Ethics [Peer Reviewed]
Date: November 2015
© 2015 Springer Science+Business Media DordrechtWe believe that the professional responsibility of bioscience and biotechnology professionals includes a social responsibility to contribute to the resolution of ethically fraught policy problems generated by their work. It follows that educators have a professional responsibility to prepare future professionals to discharge this responsibility. This essay discusses two pilot projects in ethics pedagogy focused on particularly challenging policy problems, which we call “fractious problems”. The projects aimed to advance future professionals’ acquisition of “fractious problem navigational” skills, a set of skills designed to enable broad and deep understanding of fractious problems and the design of good policy resolutions for them. A secondary objective was to enhance future professionals’ motivation to apply these skills to help their communities resolve these problems. The projects employed “problem based learning” courses to advance these learning objectives. A new assessment instrument, “Skills for Science/Engineering Ethics Test” (SkillSET), was designed and administered to measure the success of the courses in doing so. This essay first discusses the rationale for the pilot projects, and then describes the design of the pilot courses and presents the results of our assessment using SkillSET in the first pilot project and the revised SkillSET 2.0 in the second pilot project. The essay concludes with discussion of observations and results. - Assessing state stem cell programs in the United States: How has state funding affected publication trends?

- Conflicts of interest and effective oversight of assisted reproduction using donated oocytes
In: Journal of Law, Medicine and Ethics [Peer Reviewed]
Date: 2015
© 2015 American Society of Law, Medicine & Ethics, Inc.Oocyte donation raises conflicts of interest and commitment for physicians but little attention has been paid to how to reduce these conflicts in practice. Yet the growing popularity of assisted reproduction has increased the stakes of maintaining an adequate oocyte supply and (where appropriate) minimizing conflicts. A growing body of professional guidelines, legal challenges to professional self-regulation, and empirical research on the practice of oocyte donation all call for renewed attention to the issue. As empirical findings better inform existing conflicts and their potential harms, we can better attempt to reduce these conflicts. To that end, the article first describes the nature of conflicts in oocyte donation and relevant regulations and professional guidelines. We then describe studies on conflicts at four phases of oocyte donation: recruitment, screening, stimulation, and post-stimulation monitoring. Next we consider three models for conflict reduction in medicine generally: improved professional self-regulation, outright restriction like Stark anti-referral laws, or the use of conflict mediators, like in living organ donation. We ultimately conclude that improved professional self-regulation is a reasonable starting place for oocyte donation. - Positioning a Scientific Community on Unproven Cellular Therapies: The 2015 International Society for Cellular Therapy Perspective

- Risk disclosure and the recruitment of oocyte donors: Are advertisers telling the full story?
In: Journal of Law, Medicine and Ethics [Peer Reviewed]
Date: 2014
This study analyzes 435 oocyte donor recruitment advertisements to assess whether entities recruiting donors of oocytes to be used for in vitro fertilization (IVF) procedures include a disclosure of risks associated with the donation process in their advertisements. Such disclosure is required by the self-regulatory guidelines of the American Society for Reproductive Medicine (ASRM) and by law in California for advertisements placed in the state. We find very low rates of risk disclosure across entity types and regulatory regimes, although risk disclosure is more common in advertisements placed by entities subject to ASRM's self-regulatory guidelines. Advertisements placed in California are more likely to include risk disclosure, but disclosure rates are still quite low. California-based entities advertising outside the state are more likely to include risk disclosure than non-California entities, suggesting that California's law may have a modest halo effect. Our results suggest that there is a significant ethical and policy problem with the status quo in light of the known and unknown risks of oocyte donation and the importance of risk disclosure to informed consent in the context of oocyte donation. © 2014 American Society of Law, Medicine & Ethics, Inc. - The origins of human embryonic stem cell research policies in the us states
In: Science and Public Policy [Peer Reviewed]
Date: August 2013
Stem cell research has emerged as a state-level science and technology policy issue in recent years in the USA, with some states supporting research in the field and others choosing to restrict it. In this paper, we systematically explore the factors that are associated with US states' adoptions of both supportive and restrictive stem cell policies. Our analysis identifies several factors, including partisan politics, existing morality policies, the strength of a state's scientific community and the policy environment in neighboring states, which influence the adoption of state stem cell policies. Our paper aims to advance the science and technology policy literature by providing insight into the factors that push states to adopt science policies when economic development goals conflict with ethical concerns. © The Author 2013. - Compliance with donor age recommendations in oocyte donor recruitment advertisements in the USA
In: Reproductive BioMedicine Online [Peer Reviewed]
Date: April 2013
IVF using donated oocytes offers benefits to many infertile patients, yet the technique also raises a number of ethical concerns, including worries about potential physical and psychological risks to oocyte donors. In the USA, oversight of oocyte donation consists of a combination of federal and state regulations and self-regulatory guidelines promulgated by the American Society for Reproductive Medicine. This study assesses compliance with one of these self-regulatory guidelines-specifically, ASRM's preferred minimum age for donors of 21. To assess compliance, 539 oocyte donor recruitment advertisements from two recruitment channels (Craigslist and college newspapers) were collected and evaluated. Of these, 61% in the Craigslist dataset and 43% in the college newspaper dataset listed minimum ages between 18 and 20, which is inconsistent with ASRM's preferred minimum age recommendation of 21. Advertisements placed by oocyte donor recruitment agencies were more likely than advertisements placed by clinics to specify minimum ages between 18 and 20. These results indicate that ASRM should evaluate and consider revising its donor age guidelines. IVF using donated human eggs can help many patients who have difficulty having children. However, the technique also raises ethical concerns, including concerns about potential physical and psychological harms to egg donors. In the USA, oversight of egg donation relies on a combination of federal and state regulation and professional self-regulation. Governmental regulations address only limited aspects of egg donation, such as the potential spread of infectious diseases and the reporting of success rates, leaving voluntary guidelines developed by an association of medical professionals to address most issues, including ethical concerns raised by the practice. One of these voluntary guidelines recommends that egg donors should be at least 21 years of age. In this article, we analysed 539 egg donor recruitment advertisements published on Craigslist and in college newspapers to see whether fertility clinics and egg donor recruitment agencies follow this recommendation. We found that 61% of advertisements in the Craigslist dataset and 43% of advertisements in the college newspaper dataset listed minimum ages between 18 and 20 and, thus, did not follow the recommendation that egg donors be at least 21 years of age. Advertisements placed by egg donor recruitment agencies were more likely than advertisements placed by fertility clinics to list minimum ages between 18 and 20. These results indicate that the American Society for Reproductive Medicine should evaluate and consider revising its donor age guidelines. © 2012, Reproductive Healthcare Ltd.

- State stem cell policy and the geographic preferences of scientists in a contentious emerging field
In: Science and Public Policy [Peer Reviewed]
Date: December 2012
In the USA, stem cell research policy has been addressed at both federal and state levels. This paper focuses on the heterogeneous state policy environment and compares data from surveys of stem cell scientists and other biomedical researchers to evaluate the impact of supportive state policies on stem cell scientists' geographic preferences. At least early in the development of the field, permissive state policies were a strong predictor of scientists' geographic preferences. Combined with an analysis of scientists' policy awareness and explanations of their preferences, these findings suggest that supportive state science policies have influenced scientists' geographic preferences and, at least in the case of stem cell research where federal funding restrictions are prevalent, may help states to successfully recruit scientists. © The Author 2012.

- The Roles and Responsibilities of Physicians in Patients' Decisions about Unproven Stem Cell Therapies
In: Journal of Law, Medicine and Ethics [Peer Reviewed]
Date: March 2012
Capitalizing on the hype surrounding stem cell research, numerous clinics around the world offer "stem cell therapies" for a variety of medical conditions. Despite questions about the safety and efficacy of these interventions, anecdotal evidence suggests a relatively large number of patients are traveling to receive these unproven treatments - a practice called "stem cell tourism." Because these unproven treatments pose risks to individual patients and to legitimate translational stem cell research, stem cell tourism has generated substantial policy concern and inspired attempts to reduce these risks through the development of guidelines for patients and medical practitioners. This paper examines the roles and responsibilities of physicians in patients' home countries with respect to patients' decisions to try unproven stem cell therapies abroad. Specifically, it examines professional guidance from two organizations - the American Medical Association and the International Society for Stem Cell Research - and assesses physicians' professional and legal obligations to patients considering unproven stem cell therapies. Then, drawing on qualitative interviews conducted with patients who traveled abroad for unproven stem cell treatments, it explores the roles that physicians actually play in patients' decisions and compares these actual roles with their professional and legal responsibilities. The paper concludes with a discussion of strategies to help improve the guidance physicians provide to patients considering unproven treatments. © 2012 American Society of Law, Medicine & Ethics, Inc.. - Access to human embryonic stem cell lines

- The oversight and practice of oocyte donation in the United States, United Kingdom and Canada
In: HEC Forum [Peer Reviewed]
Date: March 2011
In vitro fertilization using donated oocytes is an important medical technique that provides the only option for some infertile patients to have children. The technique remains ethically contentious, however, and, as a result of this controversy, different oversight approaches have been developed in countries around the world. This paper examines the oversight and practice of oocyte donation in Canada, the United Kingdom and the United States to examine how policy choices have influenced the development and use of this medical technology. Examining per capita utilization of oocyte donation in these three countries provides evidence that supply-side policies-specifically policies affecting the compensation of potential oocyte donors-have substantially influenced the use of this technology. These results should provide useful insight for policymakers developing or revising oocyte donation policies. © 2010 Springer Science+Business Media B.V. - Policy uncertainty and the conduct of stem cell research

- Science policy and the geographic preferences of stem cell scientists: Understanding the appeal of China and Singapore
In: New Genetics and Society [Peer Reviewed]
Date: June 2010
As scientific advances increasingly pose ethical questions, policymakers must decide how, if at all, to integrate controversial lines of inquiry into existing national innovation systems. This study examines human embryonic stem cell science, a controversial but promising field characterized by an unusually heterogeneous policy environment. This study first assesses this policy environment's impact on stem cell scientists' geographic preferences and finds that permissive policies are a statistically significant predictor of stem cell scientists' preferred countries. Next, China and Singapore, two emerging leaders in the field, are examined in greater detail. China appeals to US scientists across biomedical research fields, but this appeal is largely limited to members of the Chinese disapora. In contrast, Singapore's appeal is more specific to stem cell scientists. © 2010 Taylor & Franci. - Insights from patients' blogs and the need for systematic data on stem cell tourism.

- Stem cell Tourism: Assessing the State of Knowledge
In: SCRIPTed: A Journal of Law, Science and Technology [Peer Reviewed]
Date: 2010
Policy concern about patients traveling in search of unproven stem cell based interventions (SCBIs) – a practice known as “stem c ell tourism” – has grown in recent years. These concerns are driven by the lack of convincing evidence of the safety or efficacy of these interventions and the resulting worry that individuals pursuing these unproven treatments may be putting themselves unnecessarily at risk and, perhaps, hindering legitimate translational stem cell research. This article reviews existing literature on stem cell tourism, focusing in particular on what is known about the providers of unproven SCBIs, the patients who pursue these interventions, and the outcomes of such interventions. The article concludes by highlighting gaps in the existing literature base and suggesting questions f or future investigation. - Tracking the rise of stem cell tourism

Aims: Driven by hype surrounding stem cell research, a number of clinics around the world currently offer 'stem cell therapies to patients. These unproven interventions have attracted policy interest owing to the risks they may pose to patients and to the progress of legitimate translational stem cell research, yet remarkably little data exists about the patients who undergo these unproven therapies or their experiences. We sought to characterize this patient population. Materials & methods: We developed a comprehensive data set of blogs written by patients (or their caretakers) about their experiences with unproven stem cell therapies. Results & conclusions: Analyzing these data suggests that unproven stem cell therapies are increasing rapidly in popularity and are attracting a wide range of patients - both young and old and with a diverse collection of medical conditions. These results should help clinicians advise individual patients and help policymakers devise strategies to mitigate the risks these treatments pose. © 2010 Future Medicine Ltd. - Response to Letter from Löser et al.

- Policy considerations for states supporting stem cell research: Evidence from a survey of stem cell scientists
In: Public Administration Review [Peer Reviewed]
Date: July 2008
Five states now provide funding for stem cell research, and many states are developing or debating stem cell research policies. Despite this interest, little data exist to help policy makers design policies or forecast the impact of new legislation. This article reports novel data from two surveys: one directed at those most affected by these policies - stem cell scientists - and one at a group of biomedical researchers working in less contentious fields. These data identified relatively high mobility among stem cell scientists, particularly in states with restrictive policies, and a strong preference for states with permissive policies. These findings suggest that state-specific policies may prove to be effective recruiting tools. They also suggest specific recruitment strategies and highlight the importance of first-mover advantage as states compete for the same limited pool of mobile scientists. This research aims to provide a factual basis to support ongoing policy formulation in the area. © 2008 The American Society for Public Administration. - Identifying Under- and Overperforming Countries in Research Related to Human Embryonic Stem Cells

Human embryonic stem cell (hESC) science is governed by a patchwork of policies that vary both between and within countries. To assess how this atypical environment may have influenced this field's development, publication data were analyzed to evaluate the relative performance of countries in the cumulative production of hESC-related research articles versus other areas of biomedical research. Overperforming countries generally offered permissive policy environments for hESC research, while underperforming countries were characterized by protracted policy debates and ongoing uncertainty, regardless of their current policy environment. © 2008 Elsevier Inc.

- A case for government-sponsored monitoring of preimplantation genetic diagnosis in the United States
In: Journal of Public and International Affairs
Date: March 2005
Preimplantation genetic diagnosis (PGD), a modified version of in vitro fertilization in which individual embryos are screened for specific genetic characteristics prior to implantation, provides a powerful way for parents suffering from infertility to increase their chances of having healthy children. In its various forms, PGD allows parents to screen for gender, providing a means for avoiding X-linked diseases, chromosomal abnormalities, such as translocations and aneuploidies, and single-gene disorders. Beyond these standard uses, PGD could potentially be used to select for any genetic trait, and this aspect of the technology has raised concerns that it may be used either intentionally or unintentionally for eugenic purposes. At present, reproductive medicine is only loosely regulated in the United States and new technologies, such as PGD, are almost entirely unregulated. This paper argues that given the lack of consensus regarding the ethical acceptability of PGD and embryo selection techniques, the government has an interest in gathering and reporting data on the use of PGD in the United States. Taking a proactive role now, rather than allowing the use of PGD to continue growing unscrutinized, will give society the chance to make thoughtful and deliberate decisions about its use. - Trends in the geographic distribution of human embryonic stem-cell research

- A computational scan for U12-dependent introns in the human genome sequence
In: Nucleic acids research [Peer Reviewed]
Date: 2001
U12-dependent introns are found in small numbers in most eukaryotic genomes, but their scarcity makes accurate characterisation of their properties challenging. A computational search for U12-dependent introns was performed using the draft version of the human genome sequence. Human expressed sequences confirmed 404 U12-dependent introns within the human genome, a 6-fold increase over the total number of non-redundant U12-dependent introns previously identified in all genomes. Although most of these introns had AT-AC or GT-AG terminal dinucleotides, small numbers of introns with a surprising diversity of termini were found, suggesting that many of the non-canonical introns found in the human genome may be variants of U12-dependent introns and, thus, spliced by the minor spliceosome. Comparisons with U2-dependent introns revealed that the U12-dependent intron set lacks the 'short intron' peak characteristic of U2-dependent introns. Analysis of this U12-dependent intron set confirmed reports of a biased distribution of U12-dependent introns in the genome and allowed the identification of several alternative splicing events as well as a surprising number of apparent splicing errors. This new larger reference set of U12-dependent introns will serve as a resource for future studies of both the properties and evolution of the U12 spliceosome. - The transcriptome of Arabidopsis thaliana during systemic acquired resistance
In: Nature genetics [Peer Reviewed]
Date: 2000
Infected plants undergo transcriptional reprogramming during initiation of both local defence and systemic acquired resistance (SAR). We monitored gene-expression changes in Arabidopsis thaliana under 14 different SAR-inducing or SAR-repressing conditions using a DNA microarray representing approximately 25-30% of all A. thaliana genes. We derived groups of genes with common regulation patterns, or regulons. The regulon containing PR-1, a reliable marker gene for SAR in A. thaliana, contains known PR genes and novel genes likely to function during SAR and disease resistance. We identified a common promoter element in genes of this regulon that binds members of a plant-specific transcription factor family. Our results extend expression profiling to definition of regulatory networks and gene discovery in plants. - Medical societies, patient education initiatives, public debate and marketing of unproven stem cell interventions

© 2015 Dodson and Levine. Background: Cell therapies are an emerging form of healthcare that offer significant potential to improve the practice of medicine and provide benefits to patients who currently have limited or no treatment options. Ideally, these innovative therapies can complement existing small molecule, biologic and device approaches, forming a so-called fourth pillar of medicine and allowing clinicians to identify the best treatment approach for each patient. Despite this potential, cell therapies are substantially more complex than small molecule or biologic interventions. This complexity poses challenges for scientists and firms developing cell therapies and regulators seeking to oversee this growing area of medicine. Results: In this project, we retrospectively examined the development of seven cell therapies - including three autologous interventions and four allogeneic interventions - with the aim of identifying common challenges hindering attempts to bring new cell therapies to market. We complemented this analysis with a series of qualitative interviews with experts in various aspects of cell therapy. Through our analysis, which included review of extant literature collected from company documents, newspapers, journals, analyst reports and similar sources, and analysis of the qualitative interviews, we identified several common challenges that cell therapy firms must address in both the pre- and post-market stages. Key pre-market challenges included identifying and maintaining stable funding to see firms through lengthy developmental timelines and uncertain regulatory processes. These challenges are not unique to cell therapies, of course, but the novelty of cell-based interventions complicates these efforts compared to small molecule or biologic approaches. The atypical nature of cell therapies also led to post-market difficulties, including challenges navigating the reimbursement process and convincing providers to change their treatment approaches. In addition, scaling up production, distributing cell therapies and managing the costs of production were challenges that started pre-market and continued into the post-market phase. Conclusions: Our analysis highlights several interrelated challenges hindering the development of cell therapies. Identifying strategies to address these challenges may accelerate the development and increase the impact of novel cell therapies. - Policy uncertainty, ethical considerations and the funding of stem cell science

- Policy Considerations for States Supporting Stem Cell Research: Evidence from a Survey of Stem Cell Scientists
Date: 2006
Five states now provide funding for stem cell research and numerous states are developing or debating stem cell research policies. Yet despite this interest, few data exist to help policymakers design policies or forecast their impact. This article reports novel data from two surveys: one directed at those most affected by these policies - stem cell scientists themselves - and one at a group of biomedical researchers from less contentious fields. These data identified relatively high mobility among stem cell scientists, particularly those in states with restrictive policies, and a strong preference for states with permissive policies. These findings suggest state-specific policies may prove to be effective recruiting tools. They also suggest specific recruitment strategies and highlight the importance of first-mover advantage as several states compete to recruit from the same limited pool of mobile scientists. This research aims to provide a factual basis to support ongoing policy formulation in the area.
