Sequential Increase in Complement Factor I, iC3b, and Cells Expressing CD11b or CD14 in Cutaneous Vasculitis

Figure 4

A representative micrograph showing migrated peripheral blood mononuclear cells (PBMCs) on the lower surface of porous membrane after stimulation for 48 hours with (a) diluent control or (b) 25 μg/ml iC3b. The PBMCs, stained with May-Grünwald-Giemsa, were from the subject F29. The cells in Figure 4(b) belong mostly to the monocytic lineage, though they cannot be distinguished with absolute certainty from lymphocytes.
