Figure Lengend Snippet: FFA in low concentrations promoted the osteogenic differentiation of hMSCs by inhibiting the NF-κB pathway. a FFA at 50 μM downregulated the expression of TNF , IL6 , IL8 , and ICAM1 both in PM and OM in hBMMSCs, as determined by qRT-PCR. b FFA at 50 μM could not increase ALP activity in hBMMSCs in the presence of TNF-α or LPS. Yet FFA at 50 μM increased ALP activity more in hBMMSCs in the presence of Bay117082. Human BMMSCs were treated with PM, OM, OM with FFA at 50 μM, or OM with FFA at 50 μM and TNF-α or LPS or Bay117082 for 7 days before ALP staining. c FFA at 50 μM no longer accelerated mineralization in hBMMSCs in the presence of TNF-α or LPS. Yet FFA at 50 μM accelerated mineralization more in hBMMSCs in the presence of Bay117082. Cells were treated with PM, OM, OM with FFA at 50 μM, or OM with FFA at 50 μM and TNF-α or LPS or Bay117082 for 14 days, and calcium deposition was then tested using ARS staining. d The result of quantification of ALP activity was consistent with the result of ALP staining. e The result of quantification of ARS was consistent with the result of ARS staining. f TNF-α and LPS downregulated the expression of RUNX2 and BGLAP in hBMMSCs, which had been increased by 50 μM FFA, as determined by qRT-PCR. Bay117082 further upregulated the expression of RUNX2 and BGLAP in hBMMSCs, which had been increased by 50 μM FFA, as determined by qRT-PCR. g Western blot of protein expression of p-IKK, p-IκBα, IκBα, p-P65, P65, and the internal control GAPDH. Human BMMSCs were cultured in PM or PM with FFA for 7 days before treated with TNF-α or LPS for 30 min. h Western blot of protein expression of p-IKK, p-IκBα, IκBα, p-P65, P65, RUNX2, and the internal control GAPDH. Human BMMSCs were cultured in OM or OM with FFA for 7 days before treated with TNF-α or LPS for 30 min. All data are shown as the mean ± SD, n = 3. * p < 0.05, ** p < 0.01, and *** p < 0.001.

Figure Lengend Snippet: Real-time polymerase chain reaction (RT-PCR) assay of osteogenic induction of mesenchymal stem cells (MSCs) co-cultured with peripheral blood mononuclear cells (PBMNCs) or quality and quantity control-cultured mononuclear cells (QQMNCs): a) the graphs show the relative gene expression levels of osteogenic factors (Type 1 collagen, RUNX2, and osteocalcin) (**p < 0.01, Tukey’s post hoc test). Expression of osteocalcin was undetectable at day 3. The expression levels were compared between the QQMNC group and the control and PBMNC groups. Each graph column represents a mean standard deviation (SD); n = 12 per group; b) quantification of Alizarin red S staining: MSCs were stained with alizarin red at day 14 of co-culture. Microscopic image of each well of 12-well plate (upper panel: × 40 magnification in 12 wells and lower panel: × 200 magnification) showed enhanced alizarin red staining of MSCs in co-culture with QQMNCs compared with control.
