Figure Lengend Snippet: Effect of MenSC-derived secretomes on M1-like MDM polarization. Expression of M1-and M2-associated markers was analyzed in MDMs committed to an M1-like phenotype following treatment with S-MenSCs during the polarization phase. (A) Flow cytometry analysis of M1-associated markers (CD80 and CD86) and M2-associated markers (CD163 and CD206), represented as both the frequency of positive cells (% of cells) and the geometric mean fluorescence intensity (GeoMean). (B) RT-qPCR analysis of pro-inflammatory cytokines ( IL1B , IL6 , and TNF ) and anti-inflammatory cytokines ( IL10, TGFB ). Data are presented as mean ± SEM. For n = 6 donors, normality was assessed by Shapiro–Wilk test; normally distributed data were analyzed by repeated-measures one-way ANOVA with Tukey’s post hoc test, and non-normal data by Friedman test with Dunn’s multiple comparisons. *, p < 0.05 and **, p < 0.005. NT, non-treated MDMs; S-bM, MDMs treated with secretome from basal MenSCs (S-bMenSC); S-pM, MDMs treated with secretome from IFNγ/TNFα-primed MenSCs (S-pMenSC).
Article Snippet: The following TaqMan probes were utilized for gene expression analysis: TNF (hs00174128_m1), IL6 (hs00174134_m1), IL1B (hs01555410_m1), TGFB (hs00998133_m1), IL10 (hs00961622_m1), and TBP (hs00427620_m1), the latter as reference gene.
