Xenograft OSCC mouse models. (A–D) An ectopic mouse model of OSCC. (A) OSCC-BD cells overlapped and lost contact inhibition. (B) HE staining showed that OSCC-BD cells had malignant characters. (C) The nude mice were subcutaneously injected with OSCC-BD cells. Tumor formation was observed, and neoplasms were about 1.0± 0.2 cm in size. (D) HE staining showed the neoplasm was typical squamous cell carcinoma. Scale bars, 100 μm (A) and 50 μm (B). Reproduced and modified with permission (110). Copyright © 2015, Springer Nature. (E–H) An orthotopic mouse model injected into the lateral border of the tongue of non-obese diabetes–severe combined immune deficiency (NOD-SCID) mice via HSC-3 cells. The HSC-3 bearing tumors have (E,F) ulcers, (G) neural, and (H) vascular invasion (arrows). Scale bars, 0.2 cm (E), 400 μm (F), and 200 μm (G,H). Reproduced and modified with permission (111).
