I don’t get why is possible to regrow a lot of stuff (skin, muscles, broken bones etc.), but only to a certain extend. At one moment you are suddenly not able to rebuild things.
Why is that and what determines what we can regrow?

The limits of our knowledge of biology. There is no particular reason I shouldn’t be able to regrow you from the skin cell you left on the doorknob - the DNA is all there - but nobody has any clue how you would go about doing that. (if we ever get there it will make for some interesting nature vs nurture data). Only time will tell how much we figure out in the future. For today the limits are where they are.
