Fig. 2From: Rabbit VX2 lung tumor models can form early nodal metastasesRepresentative pathology images of VX2 nodal metastases. Hematoxylin and eosin (left), and cytokeratin AE1/AE3 immunohistochemistry (right) stains demonstrate negative nodal tissue (a), isolated tumor cells (b), micrometastases (c), and macrometastases (d). The isolated tumor cells were not easily visualized by standard hematoxylin and eosin staining but were clearly seen on immunohistochemical staining. VX2 cells have strongly positive cytoplasm on immunohistochemistry. Scale bar represents 300 μmBack to article page
