Figure 2 Cyclooxygenase-2 and prostaglandin E1 receptor immunoreactivity scores in hepatocellular carcinoma tissues at different histological grades. Cyclooxygenase-2 (COX-2) expression was higher in well-differentiated tissue (Edmondson grade I-II), while EP1 receptor expression was higher in poorly-differentiated tissue (Edmondson grade III-IV). WD: Well-differentiated; PD: Poorly differentiated; HCC: Hepatocellular carcinoma.
