Figure 2

The time course of the remaining wound area. The wounds were treated with CS-NSS, CGS-NSS, CS-bFGF, or CGS-bFGF at 1 and 2 weeks. At 1 and 2 weeks, the remaining wound area did not differ among the groups to a statistically significant extent. At 2 weeks after implantation, the areas of the wounds in all of the groups were significantly smaller than at 1 week ().
