Figure 4. Immunophenotypic characterization of MSC and expression of APM components.
Panel A Flow cytometric analysis of MSC immunophenotype.
Panel B Intracellular expression of APM components was evaluated by flow cytometric analysis of MSC and Raji Burkitt’s lymphoma cell line, used as positive control. Empty profiles represent staining with specific antibodies, whereas filled profiles represent staining with isotype-matched controls. One representative experiment out of five performed is shown.
Panel C The intracellular expression of APM components in MSC was evaluated by flow cytometry, in basal conditions (white bars) and after 48 h treatment with IFN-γ (grey bars). Results are expressed as mean relative fluorescence intensity (MRFI). Means ± SD of five different experiments are shown.
