Figure Lengend Snippet: Therapeutic effects of M2-EVs@DNase I on sepsis-induced liver and kidney injury. (A-D) Serum levels of ALT, AST, UREA, and CREZ in each group. (E, F) Quantification of M1 (F4/80 + iNOS + ) and M2 (F4/80 + CD206 + ) macrophages, respectively. (G) Quantification of TUNEL-positive cells. (H) Quantitative analysis of mean fluorescence intensity of KIM-1. (I) Representative CLSM images of immunofluorescence staining for F4/80 (pink), iNOS (green), and DAPI (blue) of kidney tissues from each group. (J) Representative CLSM images of immunofluorescence staining for F4/80 (pink), CD206 (green), and DAPI (blue) of kidney tissues from each group. (K) Representative TUNEL staining images (green) with DAPI nuclear counterstaining (blue). (L) Representative CLSM images of immunofluorescence staining for KIM-1 (green) and DAPI (blue) in the renal tissues. Scale bar = 50 μm. n = 3. Data are mean ± SD. * P < 0.05, ** P < 0.01, *** P < 0.001, **** P < 0.0001.
