Abstract:
:The human histiocyte cell line, U937, with monocyte characteristics, can be induced to differentiate into macrophage-like cells when exposed to growth medium containing 1.5% DMSO. Following three days of exposure, DMSO-treated but not control U937 cells can be stimulated to release endogenous arachidonic acid from their phospholipids. Maximum release of the unsaturated fatty acid occurs with 10 microM calcium ionophore in the presence but not in the absence of exogenously added calcium ion. In addition, DMSO-treated but not control U937 cells exhibit phospholipase activity when exposed to human IgG and then anti-human immunoglobulin. These data suggest that with respect to arachidonic acid metabolism U937 cells differentiate into functional macrophage-like cells when exposed to DMSO.
