Figure 4. SRGN expression was upregulated in osteosarcoma cells. (A) Expression of SRGN by western blot in hFOB1.19 and osteosarcoma cells. (B) The expression level of SRGN in osteosarcoma cells was detected by quantitative polymerase chain reaction (qRT-PCR). Data are presented as mean ± SD. *P < 0.05.
