The inflammatory response is promoted by Nano-Se@S (8 ng/mL). A Schematic illustration of testing the aggregates of inflammatory cells at the wound site in zebrafish fin. B Representative fluorescence microscopy images in transgenic zebrafish (coro1a:EGFP) in which inflammatory cells were labeled with green fluorescence. C Quantitative fluorescence analysis of inflammatory cells at the wound site in zebrafish fin treated with Nano-Se@S in transgenic zebrafish (coro1a:EGFP). D Representative MPO (neutrophils) and CD206 (M2 macrophages) IHC images of regeneration skin tissue treated with different concentration of Nano-Se@S. Scale bars, 100 μm
