Herein, we identified bone marrow MSC (BMSC)-derived EVs harboring microRNA (miR)-29b-3p to regulate osteogenic differentiation through effects on the suppressor of cytokine signaling 1 (SOCS1)/nuclear factor (NF)-κB pathway via targeting of lysine demethylase 5A (KDM5A) in osteoporosis. Here, SOCS1 is linked to osteoporosis.
