Osteolineage cells and regulation of the hematopoietic stem cell.

Over the last 10 years, progress has been made in understanding the relationship between hematopoietic stem cells and their microenvironment, or niche. Increased knowledge of the microenvironment and its effects on hematopoiesis and leukemogenesis based on murine models may lead to the identification of relevant new therapeutic targets for leukemia. In particular, the chemokine CCL3 has potential as a mediator of leukemia-induced microenvironmental changes, as it has been found to be increased in human acute myeloid leukemia.
