Extended Data Fig. 2. Arg1+microglia co-exist with Arg1−negative-microglia in the same vicinity in P10, P28 and P100 WT mouse brain.
a, Arg1-YFP-positive microglia in male YARG mice, as recognised by α-GFP and α-ARG1 antibodies (representative image from 3 female animals). b, Arg1+microglia (arrows) and Arg1-negative-microglia (arrowheads) during mouse brain development. c, Arg1+microglia in BF/vStr at P10, P28 and P100 (representative images from 3 female animals per group). Each white dot represents a single Arg1+microglia and has been manually annotated. Scale bars, x = 50 μm, z = 10 μm (a), x = 10 μm (b), x = 1000 μm, z = 4 μm (c). Yellow squares indicate location of the corresponding images on their left; grey lines indicate the BF/vStr region.
