The BMSC/IFN-β inhibits proliferation through decreasing the proportion of S-phase cells. Flow cytometric analysis of indicated HepG2 (A) and Huh7 (B) cell co-culture with BMSC/IFN-β or control vector, and quantification of G0/G1- and S-stage cells in HepG2 (right panel; A) and Huh7 cells (right panel; B). Each bar represents the mean of three independent experiments *P<0.05.
