ABSTRACT
To study the importance of chemokine SDF-1 in surviving of acute myelocytic leukemia cells HL-60, the adhesion ability of HL-60 and expression of Bcl-2, Fas protein when SDF-1 activity was blocked by anti-CXCR4 monoclonal antibody (12G5) were compared with those detected before MAb incubation, in this experiment, HL-60 cell were cultured and co-cultured with normal marrow stromal cell. The adhesion rate was detected while the expression of Bcl-2 and Fas proteins were assayed by immunohistochemical technique when SDF-1 activity was inhibited. The results showed that cell adhesion rate of HL-60 decreased while the expression Bcl-2 decreased and Fas increased. It is concluded that inhibition of SDF-1 activity increases cell apoptosis and thus reduces life-span of leukemia cell at certain level.
