Expression of ICAM-1 by cultured biliary epithelial cells with different culture characteristics by using flow cytometric analysis: GM: cells cultured in growth medium only; TNF-α: growth medium supplemented with 100 U/ml TNF-α; INF-γ: growth medium supplemented with 100 U/ml INF-γ; CMV: cultured cells in each well incubated with 1·5 × 105 pfu murine cytomegalovirus for 3 days in growth medium. *P < 0·05; **P < 0·01, when compared with control (GM only). Results were the average of six replicates, error bars represent standard error.
