Figure 2. Effect of CDECM on the migration of hConECs and hPECs. A: The effects of chondrocyte-derived extracellular matrix (CDECM; 1 mg/ml) on human conjunctival epithelial cell (hConEC) and human pterygium epithelial cell (hPEC) migration were evaluated through a scratch wound closure assay. Scale bar = 200 μm. B: The graph shows the relative migration rate normalized to the control. C: The Transwell invasion assay tests the influence of CDECM on the invasion ability of hPECs. Scale bar = 200 μm. D: The graph shows invaded cells per area. Data are expressed as the means ± standard deviation (SD; n = 4). Statistical significance is indicated as ***p<0.001.
