a Immunofluorescence on sections of the head of a E18.5 Spi1GFP/+ embryo (PU1-GFP in green), labeled for Lyve1 (red) and CD45 (white) (60 µm maximum intensity projection) shows the presence of the conventional (white arrows) and the non-conventional pvM populations (red arrows) at this stage (n = 3). b No GFP nor Lyve1 fluorescence was observed in the Spi1GFP/GFP E18.5 dorsal cortex (33 µm maximum intensity projection) (n = 2). c Immunofluorescence on Spi1GFP/+ adult mouse brain (48 µm maximum intensity projection) (n = 3). d Immunofluorescence on sections of Cx3cr1GFP/+; Cx3cr1-Cre; Rosa26tdT mouse brain showing that conventional (white arrows) and non-conventional pvM population (red arrows) are expressing tdTomato (n = 3). e Flow cytometry analysis of Cxcr4-CreErt2; Rosa26tdT brain parenchyma, gated on living, single cells and CD64+ F4/80+ CD206+ cells. Subsequently histograms of CD45 and Lyve1 expression of the CX3CR1tdTomato population in blue, the CX3CR1+tdTomato population in red and FMO in gray (n = 3).
