From skin cell scientists could save species in danger of extinction

In California, a group of scientists from the Scripps Research Institute conducted a study and develop the first stem cells from some animals on the basis of normal cells of the skin, in that way could improve and permit the reproduction of some complicated species, at the same time to strengthen the health of specimens in captivity and prevent its extinction.

This technique known as induced pluripotency, is described in the latest edition of the online magazine, Nature Methods, a method that builds on the cells of the skin of the species at risk. Some years ago was a collection of cell samples of skin and other materials, under the responsibility of the director of genetics of the Zoo Institute for Conservation of San Diego Oliver Ryder.

Thus managed to create Frozen Zoo, at that time did not exist to work them, but after studies in California, apparently now, its operation is through insertion of genes in normal cells, thereby detonating the transformation.

Scientists initiated the study by selecting two species, the first is a primate of name Drill – it was selected by their genetic similarity with humans and because while in captivity developed diabetes – the other species is a white rhinoceros in the North, this animal was chosen by his genetic distance with primates and for being one of the species involved in the world (indicate that worldwide there are only seven copies)
With the treatment of pluripotency, also it could improve the genetic diversity of animals, making them stronger and more resistant to their environment. What that Jeanne Loring Professor of evolutionary Meurobiología of Scripps Research says is: “the most important thing is to provide these stem as a resource for other people to take some of the next steps”
Let us hope that this technique is the most appropriate, thereby preventing the extinction of most species, who knows even species that have disappeared from DNA samples, could revive by can you imagine back to the dinosaurs?
