Les cellules multipotentes sont celles que les scientifiques veulent utiliser et ce qui devient important, c'est qu'ils prélèvent les cellules qui feront partie de ce que l'on appellerait scientifiquement l'embryon proprement dit—non pas les cellules qui sont à l'extérieur qui deviendront le placenta, mais les cellules qui deviendront l'embryon.
The pluripotent cells are the cells that the scientists want to use, and what becomes important is that they're taking the cells that are part of what would be referred to scientifically as the embryo proper—not the cells that are on the outside that will become the placenta, but the cells that would become the embryo.
