B7-H1 expression on circulating monocytes.
a: Representative FACS data for B7-H1 expression on circulating
monocytes from the normal controls and gastric cancer patients.
b: B7-H1 expression is significantly higher on circulating monocytes
from the gastric cancer patients than on those from the normal controls
(P < 0.0001).
[ ], number of subjects. FACS, fluorescence-activated cell sorting.
