Seems the cells he's using are LINEAGE cells --they are no longer totipotent (are not embryonic) and have committed to a specific lineage.
In fact, it seems to me he's SPECIFICALLY saying that earlier efforts using ES cells were problematic and that that's why they're NOT doing that, this time 'round.

The above title has the word "ADULT" when in fact the cells were not taken from an adult nor are they adult stem cells. Seems the poster wants to imply something that is not true.
