Fig. 3. Impairment of wound re-epithelialization in Rac1^E-KO mice. (a,b) Micrographs of H-E-stained sections of wound-edge samples. Samples were taken from (a) Rac1^E-HET mice and (b) Rac1^E-KO mice 5 days after wounding. Yellow arrows indicate wound margin. Black arrows indicate the front of the neo-epidermis. Bar, 200 µm. (c,d) Results of histomorphometric analysis of (c) `length' and (d) `area' in wounds of Rac1^E-HET and Rac1^E-KO mice as the mean ± s.d. obtained from eight Rac1^E-KO mice and six Rac1^E-HET mice. ^***P<0.001.
