By Kate Kelland LONDON (Reuters) - In experiments that could open a new era in stem cell biology, scientists have found a cheap and easy way to reprogramme mature cells from mice back into an embryonic-like state that allowed them to generate many types of tissue. Chris Mason, chair of regenerative medicine bioprocessing at University College London, who was not involved in the work, said its approach was "the most simple, lowest-cost and quickest method" to generate so-called pluripotent cells - able to develop into many different cell types - from mature cells.{br}{br}View the Entire Article{br}
