Fig. 2. Interleukin-34 (IL-34) is produced by intestinal CD68 + tumor-infiltrating cells (TICs).

Fig. 2

A, B Representative dotplots showing IL-34-producing cells in TICs or lamina propria mononuclear cells (LPMCs) isolated, respectively, from the tumoral and non-tumoral areas of one patient with CRC. Cells were gated on live CD45 + cells and subsequently analyzed for the expression of IL-34, CD3 (A) or CD19 (B) by flow cytometry. One of five representative experiments is shown. Staining with the IL-34 isotype control antibodies is also shown. C Representative dotplots showing IL-34-producing CD68 + TICs or LPMCs isolated as above. Cells were gated on CD45 + live cells and subsequently analyzed for the expression of IL-34 and CD68 by flow cytometry. The right panel shows live CD45 + CD68 + cells expressing IL-34 in TICs or LPMCs isolated from five patients with CRC. Each point in the graph indicates the percentage of live CD45 + CD68 + cells expressing IL-34 in a single sample of a single CRC patient. Horizontal bars indicate the median values.
