The Effects of Helicobacter pylori-Derived Outer Membrane Vesicles on Hepatic Stellate Cell Activation and Liver Fibrosis In Vitro

Figure 1

Morphological characterization of H. pylori-derived OMVs. (a) Scanning electron microscopic (SEM) image of OMVs indicated the round-shaped and double-layered vesicles in various sizes (range: 50-200 nm). (b) Size distribution by intensity of H. pylori-derived OMVs based on DLS. Size distribution is determined based on the intensity of OMVs in the ultracentrifugation technique. DLS confirmed nanosized OMVs in a range of about 50 to 450 nm, peaked at 100-150 nm.
