Research Abstract

To explore the mechanism leading to leukemogenesis by TEL-AML1 fusion gene, mouse ES cells which stably express TEL-AML1 were established, and were differentiated into hematopoietic lineages including B lymphocytes. TEL-AML1-expressing ES cells were capable of differentiating into Flk1-positive mesodermal cells as well as wild-type ES cells, but numbers of produced c-kit+/Sca1+hematopoietic stem cells were significantly reduced compared to control ES cells. Expression of transcriptional factor E2a, which is essential for B lymphocyte differentiation, was retaied in TEL-AML1-expressing ES cells, and immature B lymphocytes could be producedafter 3 to 4 weeks when co-cultured on OP9 stromal cells. On the other hand, TEL-AML1-expressing hematopoietic cells did not confer any growth advantage indicating that at least other genetic abnormalities are necessary for leukemic transformation by TEL-AML1.
