Figure 4. LHX2 silencing inhibits OS growth and metastasis in vivo. (A) OS-143B cells stably expressing luciferase and the indicated genes were inoculated into nude mice (n=6), and mice were sacrificed after 5 weeks. (B) Tumor sizes were measured weekly and calculated using the following formula: V= (Length×Width²/2). (C) Orthotopic tumors were dissected and weighted. **P<0.01. (D) Representative bioluminescence and lung anatomy of the metastasis of OS cells, black arrows indicate possible metastatic lesions. Metastatic foci in the lungs were determined by luminescence signals and counted. **P<0.01. (E) Representative H&E staining of lung sections. (F) IHC analysis of Ki67 and LC3 in tumors from tumor-bearing mice. Scale bar: 100 μm.
