Divisional History and Hematopoietic Stem Cell Function during Homeostasis
We investigated the homeostatic behavior of hematopoietic stem and progenitor cells (HSPCs) temporally defined according to their divisional histories using an HSPC-specific GFP label-retaining system. We show that homeostatic hematopoietic stem cells (HSCs) lose repopulating potential after limited cell divisions. Once HSCs exit dormancy and accrue divisions, they also progressively lose the a...
متن کاملPediatric Hematopoietic Stem Cell Transplantation
The introduction and evolution of hematopoietic stem cell transplantation (HSCT) could be traced back to 1950s, to the studies on interactions among irradiation, covering spleen and bone marrow from it and injection of bone marrow cells. Today, HSCT is considered a well-established, effective and promising means of therapy for various malignant and non-malignant medical conditions, both in chil...
متن کاملAdvances in Hematopoietic Stem Cell Mobilization and Peripheral Blood Stem Cell Transplantation
Hematopoietic stem/progenitor cells (HSPCs) which give rise to different blood cell types are present within the bone marrow microenvironment, especially in flat bones such as skull, vertebrae, pelvis and chest. Interacting factors such as stromal derived factor-1/CXCR4, very late antigen-4/vascular cell adhesion molecule-1, Lymphocyte function-associated antigen-1/ intercellular adhesion molec...
متن کاملHematopoietic Stem Cell Transplantation for Thalassemia
Thalassemia is an autosomal recessive disorder associated with defective synthesis of the α- or β-chain of hemoglobin. For β-thalassemia major patients, therapeutic options are either monthly red cell transfusions and chelation therapy or allogeneic stem cell transplant. Stem cell transplant is the only curative approach and success is inversely correlated with the degree of iron overload and h...
متن کاملThe hematopoietic stem cell niche in homeostasis and disease.
The bone marrow microenvironment contains a heterogeneous population of stromal cells organized into niches that support hematopoietic stem cells (HSCs) and other lineage-committed hematopoietic progenitors. The stem cell niche generates signals that regulate HSC self-renewal, quiescence, and differentiation. Here, we review recent studies that highlight the heterogeneity of the stromal cells t...
