Effect of BMSC/IFN-β on HCC proliferation. (A) Co-culture with BMSC/IFN-β significantly reduced HepG2 and Huh7 cell growth as determined by MTT assay (*P<0.05, compared with all other groups; analysis of variance and Student’s t-test; mean±s.d. of triplicate experiments). (B) Representative micrographs (left panel) and quantification (right panel) of crystal violet-stained cells. (C) Representative micrographs (left panel; magnification × 100) and quantification of BrdU incorporating cells after co-culture with BMSC/IFN-β or control vector. Each bar represents the mean of three independent experiments *P<0.05.
