Figure Lengend Snippet: Effects of VSCC-SCs, SCC-SCs and HDFs on the activation and fusion of macrophages following crosstalk with HSC-3 cells in vitro . (A) Giemsa staining was used to examine the effects of VSCC-SCs, SCC-SCs and HDFs on the activation and fusion of macrophages following crosstalk with HSC-3 cells in vitro . Black arrows indicate activated macrophages and red arrows indicate multinucleated giant cells. (B) Immunofluorescence staining were used to examine F4/80 and CD163 expression to identify the characteristics of activated macrophages and multinucleated giant cells. White arrows indicate activated macrophages and red arrow indicate multinucleated giant cells. Quantification of (C and D) the percentage of activated macrophages and (E and F) the percentage of multinucleated giant cells in the different groups. Data are presented as the mean ± SD of one independent experiment and the independent experiments were repeated in triplicate. Statistical analysis was performed using one-way ANOVA followed by Tukey's post hoc test. * P<0.05, ** P<0.01, *** P<0.001 and **** P<0.0001. ns, not significant (P>0.05); VSCC-SCs, verrucous squamous cell carcinoma-associated stromal cells; SCC-SCs, squamous cell carcinoma-associated stromal cells; HDFs, human dermal fibroblasts.
