The expression level of FGF5, FGFR1 and MAPK signaling pathway associated proteins (p-MEK2, MEK2, p-ERK, ERK, p-MNK1, and MNK1) on control or FGF5 knockout OS cells without or with rFGF5 treatment and detected by Western blot. The results showed that FGF5 activiated the MAPK signaling. *** P <0.001 vs. Crl;  ### P <0.001 vs rFGF5-

Abbreviations: Crl, control; KO, knockout; FGF5, fibroblast growth factor-5; FGFR1, FGF receptor-1; rFGF5, recombinant FGF5; OS, osteosarcoma; MAPK, mitogen-activated protein kinase; GAPDH, glyceraldehyde 3-phosphate dehydrogenase.
