CX3CR1+, Ly6Clo monocytes are present in perihematomal brain in CX3CR1-null BM chimeras. Mice were injected intracardially with 150 ug tomato lectin to delineate vasculature. Brain slices were stained with Ly6B.2 antibody to differentiate Ly6Chi monocytes and neutrophils from Ly6Clo CX3CR1+ monocytes and Dapi nuclear stain. A) Intracardiac injection of lectin stains vasculature in the brain– 20x. B) At 72 hours after ICH, distinct subsets of amoeboid Ly6B.2+ (Ly6Chi monocytes or neutrophils) and GFP+ (CX3CR1+) monocytes are seen in the perihematomal region. 20x. C) At 7 days after ICH, amoeboid, Ly6B.2−,CX3CR1+ cells are seen in the brain parenchyma surrounding the ICH cavity. The center of the ICH cavity is filled with Ly6B.2+ (Ly6Chi) monocytes or neutrophils. Tomato lectin staining is also seen in the center of the ICH cavity, most likely due to blood brain barrier breakdown at this time point leading to nonspecific lectin staining of myeloid cells. 10x. White box indicates the inset shown in panel E. D) At 14 days, amoeboid, CX3CR1+ cells can still be seen in the perihematomal region, however more CX3CR1+ cells have a ramified morphology. No Ly6B.2+ (Ly6Chi monocytes or neutrophils) cells are found. Overall blood-brain barrier disruptio
