Expression of FGFR1 is high in osteosarcoma tissues. (A) IHC analysis of osteosarcoma and paired normal bone tissues with the FGFR1 antibody. The protein level of FGFR1 was significantly elevated in the osteosarcoma tissues (magnification, ×200). (B) Determination of the mRNA level of FGFR1 in osteosarcoma and paired normal tissues. The changes in the mRNA expression levels were consistent with the results of the IHC analysis. Data are expressed as the mean ± standard deviation. FGFR1, fibroblast growth factor receptor 1; ICH, immunohistochemisty.
