Macrophage secretory products induce an inflammatory phenotype in hepatocytes

Figure 2 Macrophage-conditioned media induces a transient change in hepatocytes. Phase contrast microscopy of HepG2 cells grown in complete media (A) for 72 h, macrophage-conditioned media (MφCM) for 72 h (B) or MφCM for 24 h followed by washing and culture in complete medium for a further 48 h (C). The images shown are representative of cells after 72 h of culture in the indicated medium.
