Figure 1. Effect of CDECM on cell viability in hConECs and hPECs. Cell viability was evaluated with the 3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxy-methoxyphenyl)-2-(4-sulfenyl)-2H-tetrazolium (MTS) assay. Human conjunctival epithelial cells (hConECs) and human pterygium epithelial cells (hPECs) were incubated with different concentrations of chondrocyte-derived extracellular matrix (CDECM) for 24 h. Values are mean ± standard deviation (SD; n = 5). Statistical significance is indicated as **p<0.01 and ***p<0.001.
