ABSTRACT
This study was aimed to investigate the importance of chemokine SDF-1 in maintaining proliferation ability of acute myelocytic leukemia cell line HL-60 when the effects of SDF-1 on HL-60 cell proliferation were inhibited. Marrow stromal cells were cultured and co-cultured with HL-60 cells, and SDF-1 activity was blocked with anti-CXCR4 McAb. HL-60 cell activity was detected by MTT while cell cycle and the expression of CXCR4 on HL-60 cell membrane were observed by flow cytometry meanwhile. The internal calcium ionic concentration in HL-60 cell was detected as well before and after treated with 12G5. The results showed that 12G5 down-regulated the expression of CXCR4 on HL-60 cell membrane; HL-60 cells at G(0)/G(1) phase increased, but decreased at S phase; survive rate of leukemia cells reduced; the intercellular calcium ionic concentration of HL-60 cell decreased after treated with 12G5. It was concluded that brockage of the SDF-1 activity may inhibit proliferation of leukemia cell at certain level.
