Figure 5. Osteopontin, LAMB3 and ITGB1 expression in lung cancer was associated with advanced clinical stage, histological grade, and lymph node metastasis.

Figure 5

Immunohistochemical staining of osteopontin, LAMB3 and ITGB1 in lung cancer tissues and paired adjacent noncancerous tissues. The staining was scored.Scoring was measured by the percentage of positive cells with the following staining intensities: less than 5% scored “0”; 5–24% scored “1”; 25–49% scored “2”; 50–74% scored “3”; and more than 74% scored “4”.
