**Figure 3. **Effect of CDECM on the detachment of corneal epithelial cells. Stained corneas from the experimental NOD.B10.*H2*^{b} mice. **A**: Hematoxylin and eosin (H&E) staining: The corneas of the NOD.B10.*H2*^{b} mice were stained 10 days (10D) after the instillation of PBS or chondrocyte-derived extracellular matrix (CDECM) five times
per day for 10D. The arrows indicate the detached corneal epithelial cells. Scale bar=100 μm. **B**: The quantitative data are presented as mean ± standard deviation (SD). ***p*<*0.05 versus the value in the control. *#*p*<*0.05 versus the corresponding value in the DS 10D group. DS 10D, desiccation stress for 10 days; PBS 10D, PBS group after
10 days of instillation; CDECM 10D, CDECM group after 10 days of instillation.
