| Description | Increased bone marrow angiogenesis is a characteristic feature of multiple myeloma (MM). New blood vessels formation is provided by recruiting vascular endothelial cells from existing capillaries or circulating endothelial progenitor cells (EPC). EPCs have distinct monocytic features and can be cultured from CD14+ cells. In addition, monocytes were shown to contribute to angiogenesis as EPCs in vivo. It has been established that myeloid progenitor cells participate in the development of endothelial precursors. In MM, it has been reported that circulating EPCs carried the same chromosomal aberrations as neoplastic plasma cells (PC). It is possible that EPCs originate from common precursor that gives rise to both PCs and endothelial cells. The purpose of our pilot study was to clarify whether myeloid cells, CD14+ monocytes (CD14+MO), in MM might carry the same chromosomal abnormalities as CD138+PC. |
