Topography effect of titanium surface on AChE activity of hBMSCs derived exosomes (n = 3). The relative numbers of the exosomes in the supernatant from hBMSCs on the SLM, SLA, SAH, and SAO samples were determined by the fluorescence values of the exosome samples at 590 nm emission detection. a–d above each bar indicate significant difference compared to SLM, SLA, SAH, SAO respectively (p < 0.05)
