MM cell-derived exosomes suppressed BMSC osteoblast formation and mineralization. (A) The quantity of OB decreased in RPMI-8226 cell-derived exosomes group. (B) The amount of mineralized nodules (von Kossa staining) was decreased in RPMI-8226 cell-derived exosomes (200 μg/mL) + BMSC group compared with the BMSC group. (C) Alkaline phosphatase became weakly after the BMSCs were cultured for 3 weeks in RPMI-8226 cell-derived exosomes (200 μg/mL) compared with the BMSC group. BMSC, bone marrow stromal cell; MM, multiple myeloma.
