Multiple myeloma has a disseminated growth pattern throughout the BM and is dependent on the migration of cells across endothelial barriers and on adhesion to other cells and BMME components.24 As HGF/c‐met signaling elicits MM cell migration and adhesion, we investigated the effects of SL1 on MM cell migration and adhesion via Transwell migration and cell adhesion assays in a co‐culture system. The gene discussed is HGF; the disease is AL amyloidosis.
