New criteria bring stem cell research one step closer to long-sought goal
Date Time New criteria bring stem cell research one step closer to long-sought goal Creating stem cells that can give rise to any cell type in the early embryo and its supporting structures, including the placenta: some call it ‘the holy grail’ of stem cell research. An international team of researchers offer new criteria to determine whether a mouse stem cell line has this much-wanted ability, known as totipotency. Fluorescent image showing labelled cells in mouse embryos and gene expression, where white is each cell of the embryo, blue cells are descendants of a single totipotent cell ...
