Research Abstract

To study the developmental impact of MLL-AF4 fusion gene on early hematopoietic development, mouse embryonic stem (ES) cells with constitutive expression of MLL-AF4 were established. When hematopoietic differentiation was examined by embryoid body (EB) formation, Tie2^+c-kit^+cells which contain early hematopoietic stem cells were significantly reduced in MLL-AF4 expressing Ebs compared to that of control Ebs.Expression array analysis indicated that MLL-AF4 works as positive regulator of gene expression up-regulating various genes. Several genes up-regulated by MLL-AF4 were known to have important roles in cell differentiation to mesenchymal lineage, whereas transcriptional regulator of hematopoietic lineage were down-regulated. These MLL-AF4 expressing pre-hematopoietic stem cells with mesenchymal nature, were unable to cause leukemia in vitroor in vivo, showing that some secondary event is necessary to cause leukemia. MLL-AF4, having the potential to influence early hematopoietic cell differentiation, may cause leukemic transformation whenaccompanied by some important additional genetic events.
