Figure Lengend Snippet: a , b UMAP embedding of 1180 macrophage nuclei from sciatic nerves color-coded by subtype ( a ) or age ( b ). c Dot plot highlighting the marker genes used to identify the macrophage subtypes from A. Marker genes can be found in Table . d Relative percentage of Mϕs subtypes across ages. Steady state epi- and endoneurial Mϕ, circulating-derived phagocytic Mϕ, and chronic-inflammation Mϕ were more prevalent in sciatic nerves from 2-3, 15-16, and 20-30 months old mice, respectively. e Dot plot showing the expression levels of the marker genes used to identify the macrophage clusters, at the different time points. Markers for resident steady state Mϕ ( Cx3cr1, Mrc1, Csf1r ) are more expressed at 2-3 months old, those for circulating-derived phagocytic Mϕ (Cd74, Hspa5, Cd44, C1qa, Grn, Cd68), are more expressed at 15-16 months old, and those belonging to chronic inflammation ( Tgfβr1, Kynu) are more expressed in the 20-30 months old samples. f Representative immunofluorescence images of sciatic nerve samples show increased CD45 + /MRC1 + Mϕs in nerves from 2-3 months old mice, CD68 + /GRN + Mϕs in nerves from 15-16 and 20-30 months old mice, and CD45 + /TGF βR1+ in nerves from 20-30 months old mice. Yellow or pink arrowheads point to CD45 + /MRC1+ or CD68 + /GRN+ or CD45 + / TGF βR1 + cells. g Quantification of the number of CD45+ cells relative to the total number of cells. n = 7 - 9 - 10, biological replicates. h Quantification of the number of CD45 + /MRC1 + cells relative to the total number of CD45 + cells. n = 4 - 4 - 5 biological replicates. i Quantification of the number of CD68 + / GRN+ cells relative to the total number of CD68+ cells. n = 6 - 6 - 5. j Quantification of the number of CD45 + /TGF βR1 + cells relative to the total number of CD45 + cells. n = 3 - 5 - 5, biological replicates. Data are presented as mean values +/− SD. Source data for panels is provided as a Source Data file.
