SDC1 and Miyoshi myopathy: To validate our observation in MM patient-derived DCs, we investigated miR-29b expression in CD11c+/CD45+ DCs retrieved from BM of six MM patients and five HDs (Figure 1c) Altogether, DCs represented the 17.67% (±2.67%) of the CD45+/CD138− cells and we were unable to find any difference in term of DCs number or iDCs-mDCs ratio between MM patients and HDs (data not shown).
