Schematic illustration of the OMD-induced regulation in hDPSCs upon LPS stimulation. OMD suppressed the LPS-induced inflammatory process, decreasing the secretion of proinflammatory factors and the activation of NLRP3 inflammasome. OMD may interact with the membrane receptor of IL1R1 and inhibit the NF-κB signaling pathway to exert a protective role during pulpal inflammation
