Other studies have demonstrated the concentration of various soluble factors, such as IL-10, IL-1β, IL-3, TNFα, stem cell factor, granulocyte-macrophage colony-stimulating factor (GM-CSF), HGF, BAFF, decorin, and CCL3, in MM microenvironment are altered by MM-MSCs [75,77,83,84,85,86,87]. This evidence concerns the gene CCL3 and Miyoshi myopathy.
