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?

Mammals can’t de-differentiate cells back to progenitor stem cells, so their ability to heal is limited.
Cells turning back into stem cells sounds great until you realize this is a major pathway for tumor formation and not good with our relatively long lifespans.
