UK Approves Human-Pig Embryo Stem-Cell Harvest

Posted by timothy on from the but-I-know-plenty-of-half-pig-humans dept.

An anonymous reader writes "British biologists have received government approval to create the world's first human stem cells from hybrid embryos, part pig, part human. The Warwick Medical School team, led by Justin St. John of the Clinical Sciences Research Institute, was granted the country's third animal-human embryo license from the Human Fertilisation and Embryology Authority, which goes into effect today (July 1)."

    The summary seems to imply that they are creating embryos which combine genetic material from humans and pigs. The article, on the other hand, says that they are taking 100% human DNA and implanting them into pig egg cells which have had their DNA removed. I think it's safe to to say that there is a huge difference between the two ideas.

      They would still have pig mitochondrial DNA, even if the nuclear DNA was all replaced.

      ...but the embryos themselves are only considered to be 99.9% human, and 0.1% animal.

      Aren't humans also animals?

      In the hybrid, the mitochondria mostly come from the egg, initially making up around half of the DNA by weight, and the team will do experiments in order to ensure that the trace of human mitochondrial DNA takes over, not least because it is designed to work with human nuclear DNA.

      Apparently they are trying to remove the Pig Mitochondria as well, or atleast make the human mitochondria dominant.

    historically cannibalistic societies in the pacific did in fact call human flesh "long-pig"

    we really **do** taste like pig

    "the Marquesas Islands of Polynesia, where human flesh was called long-pig (Alanna King, ed., Robert Louis Stevenson in the South Seas, London: Luzac Paragon House, 1987: 45-50)."
