Abstract
We investigated the relative content of circulating early (Lin–CD33+HLA-DR–CD66b–), granulocyte (Lin–CD33+HLA-DR–CD66b+) and monocyte (CD14+HLA-DRlow/–) myeloid-derived suppressor cells (MDSCs) in patients with primary multiple myeloma (MM) at the mobilization of hematopoietic stem cells (HSC). The relative count of all the studied subtypes of MDSCs in patients with both complete remission and partial response did not significantly differ from those in healthy donors. Mobilization of HSCs was not associated with any changes in the content of CD14+HLA-DRlow/– and Lin–CD33+HLADR–CD66b–, however, led to a significant increase in Lin–CD33+HLA-DR–CD66b+. Thus, carrying out the mobilization of HSCs in patients with MM maybe accompanied by the accumulation of granulocyte MDSCs in the autograft.
