ABSTRACT

AIM:

To study the biology characteristics of mesenthymal stem cells(MSCs) derived from chronic myelogenous leukemia(CML) and normal adult bone marrow.

METHODS:

Mononuclear cells from chronic myelogenous leukemia(n=19) and normal adult(n=8) bone marrow were obtained,cultured in expanded medium with low serum concentration.Cell morphology,cell cycle,immunophenotype and in vitro differentiation capacity were investigated.The differentiations of osteocytes and adipocytes were detected by von Kossa staining and Oilred O staining.The chimeric oncogene BCR/ABL and Ph chromosome,two hall marks of CML,were detected in CML derived MSCs,normal adult MSCs,CML derived hematopoietic cells and K562 cells.

RESULTS:

CML and normal adult derived MSCs showed similar characteristics in cell morphology,phenotype and growth pattern.A typital fibrablast like morphology was observed.Under suitable conditions,CML and normal adult MSCs had the similar ability to differentiate into adipocytes and osteoblasts in vitro.Moreover,CML and normal adult MSCs did not express BCR/ABL gene products and Ph chromosome was not observed.

CONCLUSIONS:

We isolated and cultured a population of cells with characteristics of multipotent stem cells from CML bone marrow.There were similar biologic characteristics and differentiation ability between normal adult and CML bone marrow-derived MSCs.
