Fig. 7From: MicroRNA-enriched small extracellular vesicles possess odonto-immunomodulatory properties for modulating the immune response of macrophages and promoting odontogenesisDPSCs-sEV polarize macrophages toward the pro-healing M2 phenotype that promotes odontogenesis in vivo. a The amounts of CD163-immunopositive M2 macrophages were remarkably increased in dental pulp tissue treated with DPSCs-sEV, while fewer CD11c-immunopositive M1 macrophages were observed, compared with the control group. The odontoblast-specific markers DSP (b) and DMP-1 (c) were significantly upregulated in dental pulp tissue incubated with DPSCs-sEV, compared with the control groupBack to article page
