It is preceded by a stage called monoclonal gammopathy of undetermined significance, from which true multiple myeloma develops in only a small percentage of cases. It was assumed that this process is associated with the accumulation of genetic mutations, but in recent years there is increasing evidence that the bone marrow microenvironment plays a key role in progression and that it can become a target for therapy that prevents the myeloma development. The review considers the role of mesenchymal stem cells, immune system cells, endotheliocytes, fibroblasts, adipocytes, osteoclasts and osteoblasts in multiple myeloma progression, as well as the impact of the sympathetic nervous system and microbiome composition.</p></abstract><trans-abstract xml:lang="ru"><p>Множественная миелома – опухоль из плазматических клеток, одно из наиболее распространенных злокачественных заболеваний крови. Ей предшествует стадия, называемая моноклональной гаммапатией неясного генеза, из которой лишь в небольшом проценте случаев развивается полноценная множественная миелома. Было принято считать, что этот процесс связан с накоплением генетических мутаций, но в последние годы появляется все больше доказательств того, что ключевую роль в прогрессии играет микроокружение костного мозга и именно оно может стать мишенью для терапии, предупреждающей развитие миеломы. В обзоре рассмотрена роль мезенхимальных стволовых клеток, клеток иммунной системы, эндотелиоцитов, фибробластов, адипоцитов, остеокластов и остеобластов в прогрессии множественной миеломы, а также влияния симпатической нервной системы и состава микробиома.</p></trans-abstract><kwd-group xml:lang="en"><kwd>multiple myeloma</kwd><kwd>monoclonal gammopathy of undetermined significance</kwd><kwd>bone marrow microenvironment</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>множественная миелома</kwd><kwd>моноклональная гаммапатия неясного генеза</kwd><kwd>микроокружение костного мозга</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Moser-Katz T., Nisha S.J., Madhav V.D. et al.
