Gene expression of A4, B2, C3, and E10 in cultured bovine capillary endothelial cells after TNF- and tumor cell supernatant is different from BAEC. Confluent ACE were cultured for 8 hours either without (C) or with 1 nmol/L TNF- (TNF) and/or with lymphoma cell conditioned supernatant (TS). The mRNA expression was analyzed by Northern blots described in the legend to Fig 2 and in Materials and Methods. The differences in the expression of B2, C3, and E10 between C and the TNF + TS group were significant (P = .027, Wilcoxon rank sum test).
