The influence of bone marrow mesenchymal stem cells-conditioned medium (BMMSCs-CM) on Toll-like receptor 4 (TLR4) concentration in the hepatocellular carcinoma cell line HepG2 by ELISA. The data shows the quantitative values of TLR4 concentration for untreated HepG2 cell group (control) and treated HepG2 cell groups with 100% BMMSC-CM for 72 h. Values are expressed as mean±SD, (n=3), the treated group (HepG2=BMMSC-CM) was compared to the control group (HepG2). (*P<0.05).
