You are absolutely wrong. If you had read Stalking the Herd you wouldn't have been ignorant enough to make that statement. I published quite a number of veterinarian autopsy reports that refute your ignorance.There are no such phenomena as cattle mutilations caused by any "non human agency" as meant by that term by one poster here or by other than other animals whether predatory or scavenger. All are explicable by natural causes, very prosaic ones. Hogwash.
First human clone embryo ready for implantation - 15 September 2003 - New ScientistThe first human cloned embryo could be implanted into a surrogate mother's womb before the end of the year, US fertility expert Panayiotis Zavos claimed on Monday.
The attempt follows months of "practising" in the lab on hundreds of hybrid embryos made by fusing human cells with empty cow eggs, Zavos told a press conference in London.
He claims to have attempted this with 600 to 700 cow eggs, and successfully created around 200 human-cow embryos. "Our replication and duplication is remarkable," he said. "We have a 40 per cent success rate".
"It's teaching us how to refine the system to a point where we can use it in humans," said Zavos, adding that he planned to disclose more at the American Society for Reproductive Medicine's annual meeting in Texas in October. He says that he has submitted his results for publication to the online journal, Reproductive BioMedicine.
To make female hybrids, he fuses the empty cow oocytes with granulosa cells from women. And to make male hybrids, he fuses the empty cow oocytes with differentiated forms of fibroblast skin cells taken from men.
Creating human/cow hybrid cloned embryos has turned out to be easier than researchers expected, said a U.K. team. Scientists from Newcastle University announced their findings during the May BIO biotechnology conference in San Diego.
The Financial Times has reported that Lyle Armstrong, leader of the human/animal hybrid embryo project explained to the conference that the process of putting human skin cell DNA in the place of the nuclei of a cow’s ovum has already produced roughly 270 hybrid embryos.
