Ly-6C^lo mouse monocytes express gene signatures not found in the human subset counterpart. (A) Bar graph depicts results from qPCR (■) and microarray (□) as relative fold change of PPARγ and PPARγ-regulated genes in mouse monocyte subsets. (B) Bar graph displays results from microarray as relative fold change of genes important for recognition and engulfment of apoptotic cells in mouse monocyte subsets. (C) Protein surface expression of selected proteins from panel B are depicted as representative flow plots. In bar graphs, negative values are more highly expressed on Ly-6C⁺ mouse monocytes and positive values are more highly expressed on Ly-6C^lo monocytes.
