Primary study of the phenotype and biological characteristics of chronic myelogenous leukemia derived mesenchymal stem cells / 白血病·淋巴瘤

ABSTRACT

Objective To isolate and study the phenotype and biological characteristics of chronic myelogenous leukemia-derived mesenchymal stem cells. Methods Cultivate the mesenchymal stem cells from chronic myelogenous leukemia in vitro, identify the immunophenotype by fluorescence-activated cell sorter (FACS), and detect the bcr-abl fusion gene by RT-PCR and FISH. Results The mesenchymal stem cells from chronic myelogenous leukemia can express the bcr-abl fusion gene. Conclusion These findings provide the evidence that the rearrangement of bcr-abl gene might happen at least more primitive than CD+34 CD-38 cells.
