The researchers said they wanted to pick them up a little bit earlier in the life cycle and then work them through to what amounts to an adult status ~ just as it happens.
They are attempting to avoid working with celltypes (embryonic stem cells) that cause cancer.
--The stem cells --
They weren't stem cells.
--Those cells really can't be differentiated from "adult stem cells". --
They can easily be differientiated from "adult stem cells" as these were differentiated and adult stem cells are NOT differentiated.
