Fig.1. Immunohistochemical results of the expression of MMP-2 (A and B)and MMP-9 (C and D) A: Expression of MMP-2 in the low grading glioma (×100). B: Expression of MMP-2 in the high grading glioma (×100). C: Expression of MMP-9 in the low grading glioma (×100). D: Expression of MMP-9 in the high grading glioma (×100). Fewer positive cells with weak staining were observed in the low grading glioma (A and C). Compared to the low grading group, more positively stained cells with dark-brown granules were observed in the high grading gliomas (B and D).
