Figure 1.

The effects of EDTA or EGTA and various inhibitors of nonintegrin receptors on initial monocyte adhesion (A) and macrophage/FBGC adhesion (B). Freshly isolated monocytes or macrophages/FBGCs (day 3 to day 7) were treated with the indicated inhibitors as described in Materials and Methods. Results are expressed as the percent adhesion of untreated control cells, n = 3 monocyte donors. From left to right: EDTA, 10 mmol/L; EGTA, 10 mmol/L; heparin, 2 μmol/L; dextran sulfate, 25 μg/ml; lipopolysaccharide (LPS), 50 μg/ml; chondroitin sulfate A (CS-A), 1 mg/ml; chondroitin sulfate B (CS-B), 1 mg/ml.
