摘要
The BM microenvironment in MM, in terms of adhesive features, is well organized to entrap circulating precursors with BM-seeking properties and is able to produce cytokines that offer them the optimal conditions for local growth and final differentiation. Likewise, the malignant B cell clone is equipped with adhesion molecules which enable the cell to establish close contacts with BM stromal cells. Furthermore a number of cytokines are released including IL-1beta and M-CSF activating /BM stromal cells/ to produce other cytokines, such as IL-6, that stimulate the proliferation of plasma cells. Finally, most cytokines produced locally, including IL-1beta, TNF-beta, M-CSF, IL-3 and IL-6, also have OAF properties, explaining why the expansion of the B cell clone parallels the activation and numerical increase of the osteoclast population.
