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.
Feedback?
