The biology of regeneration.

[studiot]

I'm glad to see the biology experts are back with us so perhaps they might explain something I have oftern wondered about please.

Humans clearly have some capacity to regenerate, as witnessed by the fact that we grow and then discard one set of teeth, before regrowing a second set as we become larger.

Presumably there is some genetic coding that controls and enables this ?

Has any research been done to try to extend this capacity more generally to other body parts or even athird set of teeth later in life now we are living longer ?

What are your thoughts ?
