Effect of bFGF on GFAP expression in astrocytes that were stimulated by LPS. LPS (2 µg/mL) was used to induce the activation of astrocytes for 24 h. Then, the effect of bFGF on astrocyte activation was investigated. (A) Western blot of GFAP at different concentrations of bFGF (25, 50, and 100 ng/mL); (B) Immunofluorescence of GFAP. * p < 0.05 versus CON, # p < 0.05, ## p < 0.01 versus LPS. All results represent at least three independent experiments; Scale bar is 50 µm.
