I think there has been some concern shown that manufacturing with IPSC's is probably not different than drug manufacturing as it is unnatural medicine, and it is a reproduced cell not in its natural state, that has been altered for the benefit of economic production and ease.
That all sounds great as an investor, if you think that the FDA won't be sending that technology back for the next 20 years when they can't even get their head around natural cell technology.
You know that these manufactured, or altered cells, are called pluripotent ( meaning many potentials ) indicating that whilst they may be good if proven over decades, they may also be very bad, like cell altering cancers, because they are manipulated.
I can't see the FDA allowing this new technology for 20 years for CYP
