bFGF was administered to the culture at different days. bFGF was necessary for optimal scar formation and the longer bFGF was present in the culture, the larger the scar (p<.05 significant linear trend, r=0.51). bFGF administration in the treatment media resulted in significantly larger scars (p<.05) compared to bFGF addition during the growth phase before treatment at T=10d.
