Photo: Grendelkhan, Wikimedia Commons Researchers at the Scripps Research Institute in La Jolla, California, and San Diego Zoo have collaborated to create stem cells from the skin cells of a dead drill monkey, an endangered monkey native to Equatorial Guinea, Nigeria and Cameroon. The scientists, speaking at the International Society for Stem Cell Research in San Francisco, hope that the "induced pluripotent stem" (iPS) cells thus created can then be biochemically persuaded into becoming sperm and egg cells. They can then be implanted into the womb of another monkey, and will hopefully form a viable foetus. It is hoped that these samples can be used in IVF programmes to improve captive breeding projects. Jeane Loring, one of the Scripps researchers, told New Scientist : "You could actually breed from animals that are dead." The team used genetically engineered viruses fitted with specific human genes to reprogramme adult skin cells into becoming iPS cells. The process worked in drill monkeys, but failed in white rhinoceros cells, implying that it may be necessary to use species-specific versions of the cells in some cases. There are also concerns that the reprogramming process can cause the iPS cells to become cancerous. However, other researchers have developed techniques for creating iPS cells without leaving the reprogrammed genes in the new cells. While the process is being used on endangered species, it would be technically possible to use it for extinct animals, using surrogate mothers from other species. Last year, for the first time, an extinct animal - the Pyrenean ibex - was cloned using skin samples and the eggs of a domestic goat, although the ibex died shortly after birth.

‘Drill Monkey’? Sounds like oilpatch slang.
Quoting Ian Malcom from Jurrasic park: Scientist spend a lot of time asking can we..., when they should be spending time asking should we.....?
Old movies like “Frankenstein” were much better at asking that all important question.
No lengthy debate required...

Isn't there a blog where I can read about this?
Somehow, this is just not as exciting as cloning a T-Rex or a Triceratops.
“Jurassic Park” was a warning. Heed it.

The FreeRepublic.com Auto Excerpt feature did that for me.
I actually *did* try to post the whole story.
