introduction: umbilical cord blood (cb) has been identified as a rich source for hematopoietic stem cells (hscs), and has provided an alternative to bone marrow transplantation. the use of ex vivo expanded cells has been suggested as a possible means to accelerate the speed of engraftment in cord blood (cb) transplantation. the main aim of our study is to find the best culture media and conditi...

Committed progenitor cells and primitive stem cells mediate early and sustained engraftment, respectively, after lethal irradiation and stem cell transplantation. Peripheral blood stem cells (PBSC) from unstimulated mice are deficient in both cell types. To study techniques to mobilize both progenitor cells and primitive stem cells from the marrow to the blood, we collected peripheral blood fro...

Acute Lymphocytic Leukemia (ALL) is a clonal myeloid disorder affecting all age groups, characterized by accumulation of immature blast cells in bone marrow and in peripheral blood. Autologous Bone Marrow Transplantation is a present treatment for cure of ALL patients, which is very expensive, invasive process and may have possibility of transplantation of malignant stem cells to patients. In t...

GlobalUseof Peripheral BloodvsBoneMarrow as Sourceof StemCells forAllogeneic Transplantation inPatientsWithBoneMarrowFailure Hematopoietic stemcell transplantation (HSCT) is a therapeutic option formany patients with bonemarrow failure.1 Bone marrowwas initially the only stem cell source available until the 1990swhen peripheral blood stem cells (PBSCs) and cord blood began to be used. Currently...

Monitoring of the JAK2 V617F allele burden in myeloproliferative neoplasms after allogeneic stem cell transplantation is useful to determine levels of residual disease and has the potential to detect early relapse and guide subsequent clinical intervention. A case is described of a JAK2 V617F-positive primary myelofibrosis patient who underwent allogeneic stem cell transplantation. Prospective ...

introduction: allogeneic hematopoietic stem cell transplantation is a potentially curative treatment modality for hematological malignancies. we evaluated the outcome of patients suffering from hematological malignancies, including acute leukemias, chronic myeloid leukemia and myelodysplastic syndrome after allogeneic transplantation. methods: all patients having hematological malignancies with...

stem cells are undifferentiated biological cells that can differentiate into specialized cells and can divide (through mitosis) to produce more stem cells. they are found in multicellular organisms. in mammals, there are two broad types of stem cells: embryonic stem cells, which are isolated from the inner cell mass of blastocysts, and adult stem cells, which are found in various tissues. in ad...
