It’s a scientific breakthrough.
Researchers in Madrid have successfully reprogrammed adult cells in living animals, creating stem cells that have the ability to grow into any tissue found in the body. Until now, these stem cells – known as pluripotent stem cells – have only ever been created in a lab after being removed from the animal. However, researchers at the National Cancer Research Centre in Madrid were able to create them in the bodies of living mice. They found that they could reprogram adult cells from the mice using a cocktail of so-called “reprogramming factors”.
“It’s something we never expected, it was a surprise and it opens up the chance to create more efficient cells than those generated in vitro,” says head team researcher Manuel Serrano.
