The South Korean government passed the Bioethics and Biosafety Act, known henceforth as the Bioethics Act, in 2003 and it took effect in 2005. South Korea's Ministry of Health and Welfare proposed the law to the South Korean National Assembly to allow the progress of biotechnology and life sciences research in South Korea while protecting human research subjects with practices such as informed consent. The Bioethics Act establishes a National Bioethics Committee in Seoul, South Korea. The Bioethics Act is the first law in South Korea to regulate research on embryonic stem cells and in vitro fertilization. Most South Korean bioethical policies rely on this act and its provisions.

The Roslin Institute was established in 1993 in the village of Roslin, Scotland, as an independent research center by the Biotechnology and Biological Sciences Research Council (BBSRC), and as of 2014 is part of the University of Edinburgh in Edinburgh, Scotland. Researchers at the Roslin Institute cloned the Dolly the sheep in 1996. According to the Roslin Institute, Dolly was the first mammal to develop into an adult from the transfer of the nucleus of an adult sheep cell into an ovum with the nucleus removed. The Roslin Institute performs genetic and medical based animal studies to help investigate human physiology and medicine and to improve agricultural research. The Roslin Institute studies embryology, cloning, hormones, and genetic alterations in animals and techniques such as Somatic Cell Nuclear Transfer (SCNT).

The US President's Council on Bioethics was an organization headquartered in Washington D.C. that was chartered to advise then US President George W. Bush on ethical issues related to biomedical science and technology. In November 2001, US President George W. Bush created the President's Council on Bioethics (PCB). Convened during a nationwide cloning and embryonic stem cell research debate, the Council stated that it worked to address arguments about ethics from many different perspectives. The organization enacted a model for analyzing bioethical issues through deliberation instead of through the consensus approach. US President Barack Obama replaced the PCB in 2009 with his Presidential Commission for the Study of Bioethical Issues.

To educate its citizens about research into chimeras made from human and non-human animal cells, the United Kingdom's Human Fertilisation Embryology Authority published the consultation piece Hybrids and Chimeras: A Consultation on the Ethical and Social Implications of Creating Human/Animal Embryos in Research, in 2007. The document provided scientific and legal background, described ethical and social issues associated with research using part-human part-animal embryos, supplied a questionnaire for citizens to return to the HFEA with their opinions, and offered a list of resources for further reading to stimulate public debate. The strategy of surveying the public provided a template for developing further policy in the United Kingdom and other countries, as well as for educating citizens on embryological research.

In 2007, the Human Fertilisation and Embryology Authority in London, UK, published Hybrids and Chimeras: A Report on the Findings of the Consultation, which summarized a public debate about research on, and suggested policy for, human animal chimeras. The HFEA formulated the report after conducting a series of surveys and debates from earlier in 2007. The HFEA issued a statement in September 2007, followed by an official report published on 1 October 2007. Their report on human-animal chimeras set a worldwide precedent for discussions of the ethical use of those embryos in labs. The HFEA's report led the UK government to pass legislature about the use of human-animal cytoplasmic hybrid embryos for research in the UK.
