Heterogeneous CD70 protein expression in osteosarcoma lesions. Immunohistochemical CD70 protein staining in one specimen of diffuse large B cell lymphoma and four osteosarcoma specimens of three osteosarcoma patients (L2531 of p363; L2792 of p369; L2826 and L3312 of p404) (Table 1) Brown-colored CD70 staining patterns and counterstaining with Mayer’s hematoxylin are displayed at a 40-fold magnification.
