A strategy to ensure that adult epidermal stem cells are safe before they are used as treatments for patients has been devised by scientists. The approach involves a clonal strategy where stem cells are collected and cultivated, genetically modified and single cells isolated before being rigorously tested to make sure they meet the highest possible safety criteria. The strategy is inspired by the approaches the biotechnology industry and regulatory affairs authorities have adopted for medicinal proteins produced from genetically engineered mammalian cells.
