| Research Abstract |
We have recently generated Evi-1-GFP knock-in mice, which can trace Evi1 mRNA level in vivo, and we revealed that Evi-1 is highly expressed at both fetal and adult hematopoietic stem cells (HSCs). In addition, we also clarified that Evi-1 positive murine HSC (KSL) function as long-term HSC by bone marrow transplantation assay, and that Evi-1 can mark long-term HSC which is the most immature hematopoietic cells. (These data are now on submission) Next, for the analysis of leukemia stem cell regulation by Evi-1, we made chronic myeloid leukemia (CML) mouse of Evi-1-GFP knockin origin by using BCR-ABL oncogene. We revealed that Evi-1 positive KSL cells had highest Evi-1 expression in these model mice which implied that Evi-1 could regulate CML stem cells. Our original analysis of leukemia stem cell is still ongoing for the purpose of establishing specific therapy of CML stem cells.
