Microvesicles from Bone Marrow-Derived Mesenchymal Stem Cells Promote Helicobacter pylori-Associated Gastric Cancer Progression by Transferring Thrombospondin-2

Bone marrow-derived MSCs (BMSCs) and thrombospondin-2-deficient BMSCs were treated with or without the supernatant of H. pylori for 12 h at a multiplicity of infection of 50, and their extracellular vesicles were collected.
