Never "totally prepared": Support groups on helping families prepare for a child with a genetic condition.

A rapid increase in the reach and breadth of prenatal genetic screening and testing has led to an expanding need for prenatal support of families receiving this genetic information. As part of a larger study investigating prenatal preparation for a child with a genetic condition, we interviewed representatives of patient advocacy groups (PAGs) who support parents post-diagnosis. Groups supporting families with Down syndrome were often local or regional, while other groups were often national or international in scope.

Clarifying the Ethics and Oversight of Chimeric Research.

This article is the lead piece in a special report that presents the results of a bioethical investigation into chimeric research, which involves the insertion of human cells into nonhuman animals and nonhuman animal embryos, including into their brains. Rapid scientific developments in this field may advance knowledge and could lead to new therapies for humans. They also reveal the conceptual, ethical, and procedural limitations of existing ethics guidance for human-nonhuman chimeric research.

How Chimeric Animal Research Impacts Animal Welfare: A Conversation with Animal Welfare Experts.

In this conversation, four experts in animal research oversight-Christopher Stodgell, Lori Hill, Robert Kesterson, and Angelika Rehrig-discuss the complexities of stem cell-based chimeric animal experiments, especially in relation to traditional animal welfare practices. Each expert shares their experiences and suggestions for how best to conduct chimeric animal research, including discussing the importance of communication and collaboration between experts in animal behavior and welfare and the investigators conducting or proposing chimeric research studies.

Moral Status and the Oversight of Research Involving Chimeric Animals.

The use of nonhuman animals in research has long been a source of bioethical and scientific debate. We consider the oversight and use of nonhuman animals in chimeric research. We conducted interviews with twelve members of embryonic stem cell research oversight committees, nine members of institutional animal care and use committees, and fourteen scientists involved in human-nonhuman-animal chimeric research in different areas of the United States.

A Conversation with Chimeric Animal Researchers.

In this conversation, three researchers from the fields of developmental biology and stem cell science-Ali Brivanlou, Lorenz Studer, and May Schwarz-speak about the importance of conducting chimeric animal experiments. The scientists describe some of the stem cell-based chimeric research being conducted in the United States, responsibilities they have in using modified animals for experiments, and things they would like the public to understand about this research. This conversation illuminates not only what chimeric animal researchers are doing in the lab but also how their work may benefit society and where this science might go in the future.
