Fig. 2: IFNβ induced dynamic changes in STAT1, STAT3, and S6 phosphorylation.

a Western blot analysis conducted after 1 or 24 h of incubation with IFNβ. Actin served as loading control; b relative densitometric quantitation of the shown gel, after normalization on actin; c, d Real-time PCR analysis of Slpi and Hgf expression in MSC exposed to IFNβ upon pathway inhibition. Data are presented as mean ± SD (n = 3)
