Scientists Breed Mice From Stem Cell Alternative

Researchers turn adult, not embryonic, skin cells into stem cells

(Newser) – Scientists in China have created mice using stem cells made from modified skin cells—hinting at an alternative to embryonic stem cells, the Washington Post reports. Separate teams used viruses to manipulate genes that caused mice skin cells to regress back into induced pluripotent stem cells—which, within a placenta sheathing and in the wombs of female mice, developed into baby animals.

The creation of stem cells from differentiated cells sidesteps many of the ethical issues of destroying healthy embryos to harvest stem cells, but raises the specter of “designer babies” and surreptitious cloning. “With just a little piece of your skin, or some blood from the hospital, anyone could have your child, even an ex-girlfriend or neighbor—and there’s nothing you could do about it,” says one researcher.

"Nothing you could do about it." ?? I should think that someone else having a copy of yourself would amount to unlawful imprisonment? Breach of privacy? come on, "nothing"???? someone else giving birth to a copy of me (would get what they deserve, but aside from that) would be enslaving me, wouldn't they? If a copy were, in fact, me? Help me out here.

Money talks. The rich will get their cloned kids. No doubt about it.
