Figure Lengend Snippet: Induction of MARCKSL1 expression in mouse DCs by wounding stimulation. (A) Immunofluorescence staining of DCs following TGF‐β1 stimulation. Red: MARCKSL1; Green: CD11c; Blue: DAPI. Scale bar = 10 μm. (B) Western blot analysis of MARCKSL1 and p‐MARCKS expression in TGF‐β1‐treated DCs. * p < 0.05. (C) RT‐qPCR analysis of MARCKSL1 mRNA expression in TGF‐β1‐stimulated 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. DAPI, 4′,6‐diamidino‐2‐phenylindole; DCs, dendritic cells; MARCKSL1, myristoylated alanine‐rich C‐kinase substrate‐like 1; TGF‐β1, transforming growth factor beta 1; CD11c, cluster of differentiation 11c.

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.
