Figure Lengend Snippet: Effect of inhibition of the tumor necrosis factor-like weak inducer of apoptosis/Fn14/NF-κB/NLRP3 pathway on the microenvironmental regulatory ability of iPDLSCs. (A) Immunofluorescence staining was used to detect the expression levels of RANKL and OPG in PDLSCs, iPDLSCs, and iPDLSCs after the downregulation of Fn14, NF-κB and NLRP3, followed by statistical analysis of the average optical density values of (B) RANKL and (C) OPG, and (D) the RANKL/OPG ratio (n=5). Scale bar, 200 μ m. (E) Immunofluorescence staining was used to detect the expression levels of CD68 and CD163 in macrophages cocultured with PDLSCs, iPDLSCs, and iPDLSCs after the downregulation of Fn14, NF-κB and NLRP3, followed by statistical analysis of the average optical density values of (F) CD68 and (G) CD163 (n=5). Scale bar, 200 μ m. Statistical analysis was performed using a one-way ANOVA. * P<0.05; ** P<0.01; **** P<0.0001. Data are presented as the mean ± SD. Fn14, fibroblast growth factor-inducible 14; iPDLSC, inflammatory PDLSC; MOD, mean optical density; NLRP3, NOD-like receptor thermal protein domain-associated protein 3; ns, not significant; OPG, osteoprotegerin; PDLSC, periodontal ligament stem cell; RANKL, receptor activator of nuclear factor-κB ligand; sh, short hairpin RNA.
