Expression of markers on macrophages cultured in serum and M-CSF.
PBMC were cultured in SFM at 5×105 cells/ml in 8-well glass slides for 7 days in the presence of 10% FCS and 10 ng/ml M-CSF. Cells were then air-dried, fixed and stained with 5 μg/ml mouse IgG1 monoclonal antibodies against CD13, CD14, CD32, CD163, CD90, mouse IgG1, proyly-4-hydroxylase, 25F9, S100A8/A9, PM-2K, TE-7, and collagen-I. Cells were then counterstained with hematoxylin to identify nuclei. Inserts indicate staining at higher magnification. Bar is 50 μm.

Image caption:
DC-SIGN+ cells are macrophages in the colo-rectal mucosa during the first sixteen hours of infection. DC-SIGN+ cells are observed in lymphoid aggregates of R-H4.2 (sacrificed four hours pi; A) and lamina propria of R-H4.1 (sacrificed four hours pi; C) and R-H16.3 (sacrificed sixteen hours pi; B and D). DC-SIGN+ cells express only occasionally MHC-II molecules (A and B, arrows), but co-express PM-2K (C) and CD68 (D) marking them as macrophages. Frozen sections of colo-rectal mucosa were labeled for DC-SIGN (Alexa-488), CD3 (Alexa-350, A, B and D), MHC-II Mamula-DR (Alexa-546, A, B and C) or PM-2K (Alexa-350, C), CD68 (Alexa-546, D) and nuclei were stained with TO-PRO®-3 (A–D). The computer-generated merged images are shown. CR, crypt; LP, lamina propria; S, submucosal connective tissue; TA, T cell area of mucosal lymphoid aggregate; HEV, high endothelial venule.

Identification of circulating PM-2K+ cells and its subsets. (a) The sequential gating strategy was shown on live and small cells (left), single cells (middle) and non-T/non-B cells (right). (b–d) PM-2K+ cells were gated against fluorescence minus one (FMO) control to identify the CCR7+CD86+ (purple gate) and CCR7−CD86+ (orange gate) subsets in PM-2K+CD14+ (green gate) and PM-2K+CD14− (red gate) cells, using appropriate FMO controls.

Image caption:
PM-2K+ cells in peripheral blood. Ficoll-isolated PBMCs from one normal individual were stained with PM-2K antibody, followed by FITC anti-mouse IgG. After washing, cells were then stained with Alexa700 anti-CD14. PM-2K expression was shown in the “monocyte” gate (green) (B) or “small cell” gate (red) (C). The boundary between PM-2K+ and PM-2K- cells was set based on the fluorescence minus one control specific for PM-2K

The gating strategy and histograms with the gating of all the antibodies by flow cytometry. Sample data from a patient with breast cancer are shown. Live cells were gated on a forward scatter (FSC)/side scatter (SSC) plot (A). These cells were then further gated to determine CD3−, CD19− (B), PM-2 K+ macrophages (C). Macrophages were further gated to determine CCR7+CD86+ M1-like macrophages, CCR7−CXCR1+ M2a-like macrophages, CCR7−CD86+ M2b-like macrophages, and CCR7−CCR2+ M2c-like macrophages in PM-2 K+CD14+ (D) and PM-2 K+CD14− (E) groups.
