From paraformaldehyde-fixed tissue, 7 μm sections were prepared, as previously described (Gray et al., 2012 (link)). In some cases, sections were fixed by acetone (Gray et al., 2012 (link)). Sections were stained with the flowing antibodies: anti-Lyve1-A647, anti-CD3ε-bio (clone 145-2C11), Goat anti-CCL20 (AF760), Polyclonal Rabbit anti-GFP (Thermo Fisher Scientific), anti-B220-A647 (RA3-6B2), anti-ICAM1-bio (3E2), anti-IL7Rα-A647 (A7R34), rat anti-scart2, Hamster anti-TCRγδ (GL3), Donkey anti-Goat-biotin Jackson immunoresearch), Goat anti-Armenian Hamster-bio (Jackson immunoresearch), Donkey anti-Rat-bio (Jackson immunoresearch), Anti-biotin-A488 (Jackson immunoresearch), Anti-biotin-Cy3 (Jackson immunoresearch). Images were captured with a Zeiss AxioOberver Z1 inverted microscope.
