A new method for generating stem cells from mature cells promises to boost stem cell production in the laboratory, helping to remove a barrier to regenerative medicine therapies that would replace damaged or unhealthy body tissues. The technique, developed by researchers at the Salk Institute for Biological Studies, allows for the unlimited production of stem cells and their derivatives as well as reduces production time by more than half, from nearly two months to two weeks. "One of the barriers that needs to be overcome before stem cell therapies can be widely adopted is the difficulty of producing enough cells...
