Figure Lengend Snippet: MARCKSL1‐positive DCs promote fibroblast activation. (A) Immunofluorescence staining of co‐cultures of TGF‐β1‐stimulated DCs and fibroblasts. Green: Phalloidin; Red: CD11c; Blue: α‐SMA; White: MARCKSL1; Cyan: DAPI. Scale bar = 10 μm. (B) Western blot analysis of α‐SMA expression in fibroblasts after co‐culture with TGF‐β1‐stimulated DCs. * p < 0.05. (C) RT‐qPCR analysis of Acta2 (α‐SMA) expression in fibroblasts after co‐culture with TGF‐β1‐stimulated DCs. * p < 0.05. (D) Validation of MARCKSL1 knockdown in DCs transfected with pLKO.1‐shMARCKSL1 under TGF‐β1 stimulation. * p < 0.05. (E) Immunofluorescence staining of fibroblast co‐cultures with MARCKSL1‐shRNA‐treated DCs. Green: Phalloidin; Red: CD11c; Blue: α‐SMA; White: MARCKSL1; Cyan: DAPI. Scale bar = 10 μm. (F) Western blot analysis of α‐SMA expression in fibroblasts after co‐culture with MARCKSL1‐shRNA‐treated DCs. * p < 0.05. (G) RT‐qPCR analysis of Acta2 expression in fibroblasts co‐cultured with MARCKSL1‐shRNA‐treated DCs. * p < 0.05. Each experiment was independently repeated three times (biological replicates). Within each experiment, three technical replicates were performed per condition and averaged prior to statistical analysis. Each data point represents one independent biological replicate. Data are shown as mean ± SEM. CD11c, cluster of differentiation 11c; DAPI, 4′,6‐diamidino‐2‐phenylindole; DCs, dendritic cells; MARCKSL1, myristoylated alanine‐rich C‐kinase substrate‐like 1; RT‐qPCR, real‐time quantitative polymerase chain reaction; TGF‐β1, transforming growth factor beta 1; α‐SMA, α‐smooth muscle actin.
Article Snippet: Cells were subsequently stimulated with 5 ng/mL TGF‐β1 (7666‐MB‐005, R&D Systems, Minneapolis, MN, USA) for 24 h. Following stimulation, DCs were washed thrice with phosphate‐buffered saline (PBS) to remove residual cytokines and resuspended in fresh medium.
