Expression of markers on macrophages cultured in serum and M-CSF.

<p>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.
