The time course of the neoepithelial length. The wounds of the CS-NSS, CGS-NSS, CS-bFGF, and CGS-bFGF groups at 1 and 2 weeks. At 2 weeks, the neoepithelial length of the CGS-bFGF group was significantly longer than that of the CS-NSS and CGS-NSS groups at 1 week ( and , resp.). At 2 weeks, the neoepithelial length of the CGS-NSS group was significantly longer than that of the CS-NSS group at 1 week (). At 2 weeks after implantation, the neoepithelial length of the CGS-bFGF group was significantly longer than at 1 week ().
