In 2015, the US National Institutes of Health announced a moratorium on funding for human-animal chimera . Beyond transplantation, a human-animal chimera could also transform the way we hunt for drugs. Currently, many new treatments may appear to be effective in animal trials, but have unexpected effects in humans.

6.1.2016 · The NIH action was triggered after it learned that scientists had begun such experiments with support from other funding sources, including from California’s state stem-cell agency. The human-animal mixtures are being created by injecting human stem cells into days-old animal embryos, then gestating these in female livestock.

It identifies a chimera as: a human embryo into which a nonhuman cell or cells (or the component parts thereof) have been introduced to render the embryo’s membership in the species Homo sapiens uncertain; a chimera human/animal embryo produced by fertilizing a human egg with nonhuman sperm;

In the past, human-animal chimeras have been beyond reach. Such experiments are currently ineligible for public funding in the United States (so far, the Salk team has relied on private donors for the chimera project). Public opinion, too, has hampered the creation of organisms that are part human, part animal.

So would you drink milk from a cow/human hybrid that produces milk that is almost identical to human breast milk? And how would you interact with a mouse that has a brain that is almost entirely human? These are the kinds of questions that we will have to start to address as a society as scientists create increasingly bizarre human/animal hybrids.

In Greek mythology, a chimera was a fire-breathing creature with physical traits of a lion, goat, and dragon.

THE PATENTABILITY OF HUMAN-ANIMAL CHIMERAS By Thomas A.

Chimera, in genetics, an organism or tissue that contains at least two different sets of DNA, most often originating from the fusion of as many different zygotes (fertilized eggs). The term is derived from the Chimera of Greek mythology, a fire-breathing monster that was part lion, part goat, and part dragon.

Though the traditional Chimera is impossible in nature in that no species has more than one head and animals can’t interbreed with other (completely different) species without human intervention (like tigons or ligers). But unlike most mythical creatures, the Chimera is already real. Though it is a far cry from the traditional Greek Chimera.
