A 28-yr-old woman with acute malignant myelosclerosis received, as primary treatment, ablative chemotherapy and total body radiation therapy followed by bone marrow transplantation from her histocompatible brother. The patient is now well more than 15 mo after bone marrow transplantation, with normal peripheral blood counts, a normal bone marrow, no evidence of graft-versus-host disease, and is...

Bone marrow transplantation is called hematopoetic stem cell transplantation (HSCT), since peripheral blood and umbilical cord blood can also be used as sources of stem cell currently. In children, bone marrow transplantation is used as a definite treatment method in many diseases including hemoglobinopaties, immune deficiencies, bone marrow failure and congenital metabolic diseases in addition...

during the last two decades conventional therapy has improved the prognosis of thalassemia. however, despite such improvement it still remains a progressive disease with treatment-related complications such as hepatitis, liver fibrosis, and cardiac disease. bone marrow transplantation (bmt) can prevent or delay progression of the aforementioned complications. the importance of clinical research...

Murine models of bone marrow transplantation show that pre-conditioning regimens affect the integrity of the bone marrow endothelium and that the repair of this vascular niche is an essential pre-requisite for successful haematopoietic stem and progenitor cell engraftment. Little is known about the angiogenic pathways that play a role in the repair of the human bone marrow vascular niche. We th...

Bone marrow fibrosis is a hallmark of primary and post ET/PV myelofibrosis. To investigated the impact of replacement of the hematopoietic system in myelofibrosis patients by allogeneic stem cell transplantation on bone marrow fibrosis, we studied bone marrow fibrosis on bone marrow samples from 24 patients with myelofibrosis before and after dose-reduced conditioning followed by allogeneic ste...

Background: Acute myeloid leukemia (AML) is characterized by the proliferation of myeloid precursors and abnormal differentiation of hematopoietic stem cells, which results in the accumulation of immature cells in the bone marrow (BM). The accumulation of these cells in the bone marrow causes molecular and cellular changes in the microenvironment of the bone marrow. The adiponectin hormone orig...

To identify cells with potential antileukemia activity following bone marrow transplantation. we have monitored immunologic reconstitution in a patient with acute lymphocytic leukemia in second remission who received intensive chemotherapy and total body irradiation followed by infusion of albogeneic histocompatible marrow. Prior to transplantation. donor bone marrow cells were depleted of T ly...

Haematopoietic stem cell transplantation remains the treatment of choice for a variety of benign and malignant blood disorders.1 In this modality Haematopoietic stem cell transplantation is the intravenous infusion of haematopoietic stem and progenitor cells to re-establish marrow function in patients with damaged or defective marrow. The procedure is called Bone Marrow Transplantation (BMT) if...

introduction: the use of cord stem cells, as a cell source for bone marrow reconstruction in patient under hematopoietic stem cell transplantation is enhancing. the amount of cd34+cells collected from cord blood compared to peripheral blood and bone marrow are less, but their collectionprocesure is easier. delay in freezing has negative effect on cells surveillance and reduce their ability in t...
