The proliferation of L02 cells.

<p>The THP-1 cells differentiated to mTHP-1 cells after incubation with PMA (40 ng/ml) for 48 h. Subsequently, Culture supernatant of mTHP-1 cells was harvested in the presence of exogenous HCV core protein (10 µg/ml) at 24 h. (A) Proliferation curve of L02 cells which were cultured in 20% of mTHP-1 cells culture supernatant and 80% of complete medium. *<i>p</i><0.05 indicates alpha value as compared to control groups; (B) p-ERK protein was up-regulated in L02 cells by co-culturing mTHP-1 cells in the presence of the HCV core protein (10 µg/ml) at 24 h. The L02 cells, L02 cells only co-cultured with mTHP-1 cells, L02 cells treated with HCV core protein (10 µg/ml) respectively as control.
