Pretty interesting and fascinating stuff. I wonder how far this science will develop in our lifetime. In the video they said it was very difficult to build an organ from scratch, but if you have a prexisting 'scaffold' of an organ, consisting of protein and such; sans cells, you can then implant human cells to turn it back to a living organ.
Towards the end there is a little section on how a 3d printer was used to effectively 'print' a heart, with cells used instead of colours in the cartridge. The heart actually beat when transplanted. After development, we definitely could be looking at factories which pretty much mass produce body parts.
Which of course is just the first step. After this, undoubtedly there'll be a shift towards actually improving what we have. You can just imagine how much of a booming market it'll be as people wish to improve the longevity and effectiveness of our bodies. But shit, such companies are going to be so powerful.

Organ scaffolding looks very promising. It's pure brilliance.
Put your own cells into an organ shell and make it yours in a few days.
