Monitoring for mutation is a very tricky thing, it's like you would need a kind of immune system. But if we can do that, it truly would be tissue engineering, and spare parts for everybody would be around the corner.

Seriously though, it seems to me that growing something like a heart, which has large-scale structure, would be a lot harder than just growing a few different layers of tissue.
The future will either be awesome, or scary.
