Fig. 4.
Effect of MCP-1 on intracellular [Ca2+]i in differentiating monocytes. Cells (5 × 106/mL) were incubated with Indo-1 probe (2 μg/mL final) at 37°C for 30 minutes, washed, and exposed in cuvette (1 × 106/mL) to recombinant MCP-1 (10 ng/mL) or RANTES (10 ng/mL) or FMLP (1 × 10−7 mol/L) in the presence of 1 mmol/L extracellular Ca2+. One representative experiment of 3 is shown in (A). (B) Average values obtained in 3 independent experiments with monocytes from different donors.
