Hepatic stellate cells may be potential effectors of platelet activating factor induced portal hypertension

Figure 5 Effect of PAF concentration on PGE₂ synthesis in cirrhotic hepatic stellate cells. Cell were placed in serum-free medium after overnight culture, and were challenged with PAF 24 h later. PGE₂ in the medium was measured by ELISA after 15 min incubation. ^aP < 0.05, ^bP < 0.01 vs vehical; ^cP < 0.05, ^dP < 0.01 vs control.
