Popis: Human cytomegalovirus (HCMV) infection can cause delayed leukocyte recovery after bone marrow transplantation and often associated with suppression of granulocyte/macrophage progenitor. Leukocyte lineage may be one of the major sites of HCMV infection. However, whether HCMV can interfere with CFU-GM formation and induce apoptosis in granulocyte/macrophage progenitor have not been well investigated. Human bone marrow mononuclear cells (Ficoll), promyelocyte cell line HL-60 and HCMV AD169 strain were co-cultured. Each bone marrow specimen was HCMV DNA and HCMV IgM negative by PCR and ELISA test. Our results showed that HCMV significantly inhibited the formation of CFU-GM as shown in two different concentrations of viral infection groups: 139.26 ± 5.42 (2×105pfu/ml), and 124.19 ± 8.82 (2×106pfu/ml) (colonies/2×105cells/ml, n=26). These were significant differences compared with the blank control group (P
