Figure S2: H&E and Masson-Trichome staining of 10-12 week old tumors and other tissues. H&E staining of tumors and the corresponding lung and liver tissues is shown in panels A-C respectively. Masson-Trichome staining for collagen for the same sections is shown in panels D-F respectively. Transformed cells can be identified as pleomorphic, spindle shaped cells invading into muscular region (A). The crescent shaped nucleus in the spindle shaped neoplastic cells is indicated with arrows in the inset of panel A (magnification 100×); cytoplasm is stained dark red and it is surrounded by blue colored connective tissue (collagen) as shown in panel D. Metastatic tumor cells present in lung (B&E) and liver tissues (C&F) have been indicated with an arrow in the insets of the corresponding panels.
