Xenotransplantation in the Age of Genome Editing: Results From the Expert Report for the Federal Ethics Committee on Nonhuman Biotechnology With a Special Focus on Animal Ethics.

Background: The Federal Ethics Committee on Non-Human Biotechnology (ECNH) of Switzerland is an independent expert committee appointed by the Federal Council and mandated to advise the federal authorities from an ethical perspective in the field of nonhuman biotechnology and gene technology. Due to recent developments in the field of xenotransplantation after the introduction of genome editing technologies, the ECNH has commissioned an expert report on the ethical questions of xenotransplantation with a focus on animal ethics. The subject of the inquiry is, in particular, if current developments in the field of xenotransplantation raise new questions regarding ethics in the nonhuman realm or if existing questions have to be re-examined and answered anew.

Toward a common interpretation of the 3Rs principles in animal research.

Many scientific breakthroughs have depended on animal research, yet the ethical concerns surrounding the use of animals in experimentation have long prompted discussions about humane treatment and responsible scientific practice. First articulated by Russell and Burch, the 3Rs Principles of Replacement, Reduction, and Refinement have gained widespread recognition as basic guidelines for animal research. Over time, the 3Rs have transcended the research community, influencing policy decisions, animal welfare advocacy and public perception of animal experimentation.

Interdisciplinary Animal Research Ethics-Challenges, Opportunities, and Perspectives.

Can nonhuman animals be used for the benefit of humans in a scientifically and morally justified manner and, if yes, how? Based on our own experiences as scholars from various academic backgrounds, we argue that this question can only be answered as an interdisciplinary and international endeavor, considering insights from research ethics and animal ethics as well as scientific and legal aspects. The aim of this article is to contribute to the foundation of the emerging field of animal research ethics. In doing so, we describe the following seven phases of animal research experiments: ethical, legal and social presumptions (phase 0), planning (phase I), review (phase II), conduct of experiments (phase III), publication/dissemination (phase IV), further exploitation of results (phase V), and evaluation (phase VI).
