Immunohistological localization of resident Clec9A⁺ DCs and migratory CD1a⁺ DCs in LNs. (A–E) Frozen LN sections were stained for Clec9A (brown) and CD1a (green). (F and G) Frozen LN sections were stained for Clec9A (brown) and CD3 (green). Representative results of four independent experiments are shown. Bars, 10 µm.
