Description
The iperactivation of self-renewal mechanisms, like Hedgehog (HH) pathway, which govern the refuel of Multiple Myeloma neoplastic clone, is critical to relapse events. The bulk of current knowledge is mainly based on the CD138+ cells molecular characterization, but in the light of the recent evidences, which attributed growing relevance to immature precursor clones, we become aware that multiple myeloma disease heterogeneity have more deepen roots.
