It all depends on how efficiently and quickly one can grow an organ via stem cells.
The general consensus would be yes. Organs grown via stem cells would not have the immuno-rejection problems that donated organs have. The immune system would recognise such organs as being self and will not attack them, like they do with donated organs from someone else.
But if it's quicker to just use a donated organ, perhaps that would be used instead.
