MMP-9 Knockdown Inhibits Oral Squamous Cell Carcinoma Lymph Node Metastasis in the Nude Mouse Tongue-Xenografted Model through the RhoC/Src Pathway

Figure 3

Knockdown of MMP-9 suppressed OSCC cell interactions between endothelial cells and xenografted tumor angiogenesis. (a) MMP-9/shRNA transfection suppresses microvascular density (MVD) by IHC. (b) Knockdown of MMP-9 could decrease cell adhesion to endothelial cells by the adhesion assay. (c) Knockdown of MMP-9 could decrease cell transendothelial migration between endothelial cells. All data are shown as the . , compared with the control group.
