| Research Abstract |
We demonstrated ultradian oscillation of Hes-1 expression in single hematopoietic progenitor cells separated from murine fetal liver. Hematopoietic progenitors introduced with MLL-AF9 fusion gene cause leukemia in in vivo model. When progenitors derived from Hes-1 knockout mice were used, the Hes-1-knockout cells with MLL-AF9 caused earlier death than wild-type cells, which indicated that Hes-1 works as tumor suppressor gene in MLL-AF9 leukemia.
