Figure 4. Effect of CDECM on the conjunctival goblet cell densities. A: The conjunctivas of the inferior fornices from the PBS and chondrocyte-derived extracellular matrix (CDECM) groups were
stained with periodic acid Schiff (PAS). The arrows indicate the conjunctival goblet cells. Scale bar=200 μm. B: The quantitative data are presented as mean ± standard deviation (SD) *p<0.05 versus the value in the PBS group. #p<0.05 versus the corresponding value in the DS 10D group. DS 10D, desiccation stress for 10 days; PBS 5D, PBS group after 5
days of instillation; PBS 10D, PBS group after 10 days of instillation; CDECM 5D, CDECM group after 5 days of instillation;
CDECM 10D, CDECM group after 10 days of instillation.
