Proteom usage

[A23]

Hi,

 

do we know what happens if some human substance, for example hormons like Hgh, testosterone, or EBP1 were used locally in application ?

 

-Could it be that local effects arise so that for example cutted finger could be made "regrowing" ?

 

-may the local affect other parts of the body ? (for example if used, less dramatically, in "aesthetic" on some organs, could such have effect on other part of the body)
