Figure Lengend Snippet: TNF-α mediates TLR expression and NF-κB p65 signaling in PBMCs. (A) Western blotting was performed to detect the protein levels of TLR3, TLR4, TLR5, p65 and p-p65. Protein expression of (B) TLR3, (C) TLR4, (D) TLR5 and (E) p-p65/p65 presented as bar diagrams. β-actin was used as an internal control. *P<0.05, **P<0.01 vs. control. NF-κB, nuclear factor-κB; p-, phosphorylated; PBMC, peripheral blood mononuclear cell; TLR, Toll-like receptor; TNF-α, tumor necrosis factor-α.

Nuclei were stained blue. Scale bar = 100 μm. Quantification of the number of periostin + αSMA + F-Myo and periostin + αSMA - F-Act in each high-power field (HPF). n = 5 mice at each time point after MI. d Flow cytometry of fibroblasts isolated from hearts of C57BL/6 J WT and Pdgfra-CRE:tdTomato mice. Total cardiac fibroblasts were lineage traced by pdgfrα. F-Myo and F-Act were marked with antibodies against periostin-AF488 and αSMA-AF647. Quantification of the pdgfrα + fibroblast ratio in live cells, periostin + fibroblasts ratio in pdgfrα + fibroblasts, periostin + αSMA + F-Myo ratio in pdgfrα + fibroblasts, and periostin + αSMA - F-Act ratio in pdgfrα + fibroblasts. n = 5 mice at each time point after MI. e Spatial distribution of the F-Act and F-Myo subpopulation in mouse heart sections from sham and 10 days post-MI conditions, visualized through the integration of scRNA-seq and stereo-seq methodologies. c, d Data are the mean ± SEM and p -values are displayed in the bar charts, one-way ANOVA followed by Tukey’s multiple comparisons tests.
