CD83 and cancer: By studying metastasis in bone marrow-derived mesenchymal stem cell (BM-MSC)-driven lung cancer models, microarray time-series data analysis by systems biology approaches revealed BM-MSC-induced signaling triggers early dissemination of CD133<sup>+</sup>/CD83<sup>+</sup> cancer stem cells (CSCs) from primary sites shortly after STAT3 activation but promotes proliferation towards secondary sites.
