Hair transplantation helps with scarring. How about adding KGF to the mix?

At Imperial College London, Claire Higgins, a professor of bioengineering , and her collaborators, performed a pilot clinical study in which they transplanted hair follicles into human skin scars.   The transplanted hair follicles helped remodel the scarred skin to create functional tissue.

Follicle transplantation may become a clinically approved treatment to reduce scar formation and remodel preexisting scar tissue.

How about adding the healing power of keratinocyte growth factor (KGF) into the mix?
