TF: Tissue factor, VEGF: Vascular endothelial growth factor, OPN: Osteopontin

No differences were found for gastric and pulmonary tissue sections in our immunohistochemical examinations. All cases showed positive reactivity for tissue factor, five cases showed positive reactivity for vascular endothelial growth factor (Case 2, 3, 4, 5, and 6), and three cases showed positive reactivity for osteopontin (Case 3, 5, and 6).
