摘要：
A flow cytometric analysis of five B cell chronic lymphocytic leukemic (B-CLL) cell lines was undertaken using 129 unknown reagents from the blind panel (BP) and 72 reagents from the known CD panel obtained from the Fourth International Leucocyte Differentiation Conference and Workshop, B cell section (Vienna, 1989). The five cell lines examined were: SeD (PNAS 75, 5706, 1978), B-CLL-LCL (BLOOD 71, 9, 1988), JVM-HH and JVM-2(INT J CAN 38, 531, 1986), and WR # 1 (TH and BD). The reagents were # 1-129 (blinded panel) and reagents 1-44 and 53-84 (CD panel with CD23 reagents missing). Positivity was defined as greater than 30% of the cells having a three fold increase or more in mean channel fluorescence. Fourty-three reagents of the blinded panel were negative by these criteria while all remaining reagents were positive on all five lines. SeD showed the lowest reactivity; B-CLL-LCL and JVM-2 showed the most reactivity; JVM-HH and WR # 1 were intermediate. The known CD panel confirmed the reactivity of the blinded panel. An average immunophenotype was constructed and compared to published normal EBV lymphoblastoid cell lines and several differences were noted. There was an absence or significant decrease in the expression of CD19, CD21, CD22 and CD37 while there was an increased expression of CD38, CD54, CD74 and CD76. The heterogeneity observed between the B-CLL lines may in part be due to polymorphisms but is more likely to represent the underlying heterogeneity seen in common and familial B-CLL. In addition the variation in CD expression may be related to the effects of EBV transformation.
