Histological analysis of nude mice tumors. HSC2 or HSC2/EGFP (5 × 106) were inoculated into BALB/c nude mice subcutaneously to make each tumor mass. Each tumor was dissected out, fixed in neutral-buffered formalin, embedded in paraffin and stained with hematoxylin and eosin. Histological analysis of these tumors showed squamous cell carcinoma tissues including from highly to poorly differentiated areas, but teratomas were not observed (Bar  =  50 μm)
