Objective To observe the connexin protein 43 (Cx43) expression levels in BMSCs of acute leukemia before and after chemotherapy and normal BMSCs and study the communication function between cells. Methods In in vitro cultured BMSCs of acute leukemia before and after chemotherapy and normal BMSCs
the Cx43 expression levels were detected by immunochemistry and the difference of gap junction intercellular communication (GJIC) were examined by using dye transfer technique. Results In the BMSCs of acute leukemia before and after chemotherapy and normal BMSCs
the positive rate of Cx43 expression was (88.0±3.5)%
(12.0±2.4)% and (52.0±3.1)% respectively
average optical density value of stromal cells were (175.08±8.34)
(45.42±3.71) and (94.33±7.20) and the cell number through dye transmission of stromal cells were (9.20±0.35)
(1.84±0.33) and (4.07±0.53). Conclusion Cell-cell communication function of BMSCs of acute leukemia before chemotherapy is significantly lower than that of normal BMSCs and BMSCs of acute leukemia after chemotherapy.
