Figure 4: Immunohistochemical validation of laminin-111 expression in well and poorly differentiated OSCCs. (a) External positive control. (b) Internal positive control. (c) Photomicrograph showing intense staining around the tumor islands in well-differentiated SCC (40×). (d)Photomicrograph of laminin expression in poorly differentiated SCC (loss of integrity around the tumor islands) (20×)
