Effects of the conditioned medium of BMSCs on immunomodulation. a Real-time qPCR analyses of CD206, TGF-β, VEGFA and PDGFB mRNA expression in RAWs at day 1 (n = 3). b Real-time qPCR analyses of IL-1 and IL-6 mRNA expression in RAWs at day 1 (n = 3). c Results of flow cytometry, percentage of CD86-positive or CD206-positive cells. d Alive RAWs were gated based on forward scatter and side scatter. e Statistical results of CD86-positive and CD206-positive RAWs (n = 6). ^&P < 0.05 compared to Blank, ^&&P < 0.01 compared to Blank, *P < 0.05 compared to C, **P < 0.01 compared to C, ^#P < 0.05 compared to O-N, ^##P < 0.01 compared to O-N
