LL PRESENT FORMS OF THERAPY for acute myelocytic leukemia (AML) injure or destroy normal as well as leukemic cells. The action of anti-metabolic chemotherapeutic drugs is largely directed at disrupting flucleic acid synthesis and, thus, replication of cells. The alkylating agents and whole body radiation are effective in reducing cell production by slowing the generative cycle and directly kill...

herein we describe a case of intraocular melanoma in a17-year old leukemic patient.   the history, histological findings of the enucleated eye, blood and bone marrow of the patient were investigated. the enucleated eye contained epitheloid cell type melanoma instead of leukemic cell infiltration.  we conclude that intraocular malignant melanoma can occur in acute lymphoblastic leukemia.

Acute myelogenous leukemia (AML) is typically a disease of stem progenitor cell origin. Interestingly, the leukemic stem cell (LSC) shares many characteristics with normal hematopoietic stem cells (HSCs) including the ability to self-renew and a predominantly G(0) cell-cycle status. Thus, although conventional chemotherapy regimens often ablate actively cycling leukemic blast cells, the primiti...

BACKGROUND Criteria for good candidate antigens for immunotherapy of acute myeloid leukemia are high expression on leukemic stem cells in the majority of patients with acute myeloid leukemia and low or no expression in vital tissues. It was shown in vaccination trials that Receptor for Hyaluronic Acid Mediated Motility (RHAMM/HMMR) generates cellular immune responses in patients with acute myel...

In three patients with chronic myelocytic leukemia who were heterozygous at the X-linked glucose-6-phospháte dehydrogenase locus, lymphocytes were studied to determine if they had the same stem cell origin as the leukemic myeloid cells. Normal tissues such as skin had both B and A glucose-6-phosphate dehydrogenase isoenzymes, but the leukemic myelogenous cells displayed only one isoenzyme type,...

The chemokine stromal cell-derived factor-1 (SDF-1) and its receptor CXCR-4 (fusin, LESTR) are likely to be involved in the trafficking of hematopoietic progenitor and stem cells, as suggested by the reduced bone marrow hematopoiesis in SDF-1-deficient mice and the chemotactic effect of SDF-1 on CD34+ progenitor cells. Migration of leukemic cells might also depend on the expression of chemokine...

Background: Several studies have demonstrated the immunosuppresive effects of mes-enchymal stem cells (MSCs) in allogeneic or mitogenic interactions. Cell-cell contact inhibition and secretion of suppressive soluble factors have been suggested in this re-gard. Objective: To investigate if adipose derived MSCs could inhibit Jurkat lym-phoblastic leukemia T cell proliferation during coculture. Me...
