Anthony Atala's description of the research about how to build or regenerate organs to be used in transplants.
This TED talk is very powerful, fascinating and enthusiastic.

These topics and the current state of the research in these fields seem really to be science fiction but are real.
People will be allowed to access cell banks where to leave their healthy cells taken as biopsy from important organs, to be preserved for eventual later use.
When needed, the saved cells could be used to rebuild the failed organs to be transplanted.
