Figure 3. Semiquantitative evaluation of histochemical and immunofluorescence data. A: Corneas cultured at the air-liquid interface. The total numbers of corneas examined per group were: E=3, WE=3, WET=7; WT=6. B: Corneas cultured in immersed conditions. The total numbers of corneas examined per group were: E=3, WE=3, WET=3; WT=4. C: Comparison of semiquantitative data for control E and wounded corneas (WT; wounded after prior removal of the epithelium and limbus then cultured in the presence of added TGF-β1) between the air-liquid and immersed conditions. The total numbers of corneas examined per group were: AL/E=3, IM/E=3, AL/WT=6; IM/WT=4. In all cases, significant differences are indicated by * (p<0.05).
