Figure Lengend Snippet: A. Representative confocal images of Aβ plaques (6E10), microglia (Iba1) and CD68 showing diffuse microglial phagocytosis away from plaques in sham compared to localized phagocytosis around plaques in PBM-treated animals. B. Quantitative analysis of total and activated microglia show no overall differences in the neuroinflammatory environment surrounding Aβ plaques. (Unpaired t-test). C. Analysis of the distribution of CD68+ microglia shows a trend of higher concentration of phagocytic cells in contact with plaques, and decreasing phagocytosis away from plaques. (Two-way ANOVA).

Figure Lengend Snippet: MLPS cells trigger M2-like polarization of monocytes in non-contact co-cultures. ( a , b ) Representative images of H&E staining of FFPE sections from #37 ( a ) and #47 ( b ) MLPS tissues acquired at 200× magnification. ( c , d ) Primary MLPS cells obtained by enzymatic digestion of 37 ( c ) and #47 ( d ) tumor tissues, visualized by phase contrast microscopy (left) and fluorescent microscopy after immunostaining with anti-vimentin and anti-cytokeratin Abs (right). Nuclei were stained blue with DAPI. Original magnifications: 200× (left) and 400× (right). ( e , f ) Human monocytes were co-cultured with #37 ( e ) and #47 ( f ) primary MLPS cells in an in vitro non-contact co-culture for 72 h and then analyzed for CD68 and CD163 expression by flow cytometry. ( e , f ) Percent variation of CD68 and CD163 on monocytes collected after non-contact co-culture, compared to control monocytes. ( g , h ) After co-cultures with #37 ( g ) and #47 ( h ) primary MLPS cells, CMs from monocytes were analyzed for the content of CC2, IL-10, and IL-12 by a dot plot assay. The pixel density of each spot was measured using NIH Image J 2.0 software developed by the US NIH, USA and positive control spots were used to normalize results between the membranes. The intensity of each spot was averaged over the duplicate spots and expressed as percentage of each cytokine or chemokine spontaneously secreted by control monocytes (monocyte CM), considered as 100% (dashed line). Data represent mean ± SD from three experiments performed in duplicate with * p < 0.05, ** p < 0.005.
