Figure 3. Effect of CDECM on the remodeling of the extracellular matrix in hConECs and hPECs. The samples were immunostained for matrix metallopeptidase 9 (MMP-9), tissue inhibitor of metalloprotease 1 (TIMP-1), TIMP-2, and fibronectin. A: The membranes were photographed with the Fusion FX image acquisition system. The graphs show the densitometry quantification of MMP-9 (B), TIMP-1 (C), TIMP-2 (D), and fibronectin (E), compared with the untreated human pterygium epithelial cells (hPECs). β-actin was used as the control. Values are mean ± standard deviation (SD; n = 5). Statistical significance is indicated as *p<0.05 and **p<0.01.
