PPL Therapeutics plc, of Edinburgh, Scotland, said it has demonstrated the possibility of producing multipotential stem cells without using an embryo intermediate. The company said its U.S. subsidiary, PPL Therapeutics Inc., was able to derive beating myocardial cells from skin cells via a multipotential stem cell intermediate. PPL said the novelty in its approach is to "revert" fully differentiated skin cells into stem cells and then transform those cells into cells of another type. The work was done in bovine cells using funding from the U.S. government under its Advanced Technology Program. PPL's managing director, Ron James, presented the discovery at a meeting of the British Fertility Society in London on Friday.
