Chronic myeloid leukemia (CML), a hematopoietic stem cell disorder, cannot be eradicated by conventional chemotherapy or the tyrosine kinase inhibitor (TKI) imatinib mesylate (IM). To target CML stem/progenitor cells we investigated BMS-214662, a cytotoxic farnesyltransferase inhibitor, previously reported to kill non-proliferating tumor cells. IM or dasatinib alone reversibly arrested prolifer...

Dissociation of graft-versus-leukemia (GvL). effects from graft-versus-host disease (GvHD) is the ultimate goal of allogeneic hematopoietic stem cell transplantation (alloHSCT) in the treatment of hematological malignancies. The pivotal role of donor T cells in both anti-leukemic and anti-host reactivity of allogeneic stem cell grafts has been known since the first transplants for fatal leukemi...

Whether or not FLT3 mutations are present and expressed within a leukemic hematopoietic stem cell has engendered some controversy. New evidence has now been presented on this issue that could change the way we manage the disease in the future.

There is significant morbidity and mortality from pneumonia in leukemic and bone marrow transplant patients. We sought to explore the diagnostic yield of bronchoalveolar lavage (BAL) in these patients with new pulmonary infiltrates. A retrospective chart review of approximately 200 Non- human immunodeficiency virus (HIV) leukemic and Hematopoietic stem cell transplantation (HSCT) patients who u...

SUMMARY Profound regression followed hypophysectomy in 31% of rats with stem-cell erythroblastic leukemias induced by a set of pulse doses of a lipid emulsion of 7,8,12-trimethylbenz(a)anthracene. In the favorable cases, evidence of improvement following hypophysectomy comprised prolongation of life, decreased leukocytosis in circulating blood, diminution or disappearance of histological signs ...
