Osteolineage niche cells initiate hematopoietic stem cell mobilization.
Recent studies have implicated bone-lining osteoblasts as important regulators of hematopoietic stem cell (HSC) self-renewal and differentiation; however, because much of the evidence supporting this notion derives from indirect in vivo experiments, which are unavoidably complicated by the presence of other cell types within the complex bone marrow milieu, the sufficiency of osteoblasts in modu...
متن کاملFancb deficiency impairs hematopoietic stem cell function
Fanconi anemia (FA) is a genetic disorder characterized by bone marrow failure, variable congenital malformations and a predisposition to malignancies. FANCB (also known as FAAP95), is the only X-linked FA gene discovered thus far. In the present study, we investigated hematopoiesis in adult Fancb deficient (Fancb(-/y)) mice and found that Fancb(-/y) mice have decreased hematopoietic stem cell ...
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 کاملDiabetes Impairs Stem Cell and Proangiogenic Cell Mobilization in Humans
OBJECTIVE Diabetes mellitus (DM) increases cardiovascular risk, at least in part, through shortage of vascular regenerative cells derived from the bone marrow (BM). In experimental models, DM causes morphological and functional BM alterations, but information on BM function in human DM is missing. Herein, we sought to assay mobilization of stem and proangiogenic cells in subjects with and witho...
متن کاملThe hematopoietic stem cell niche.
Hematopoietic stem cells (HSCs) possess the ability to self-renew and to differentiate to mature progeny along multiple different hematopoietic lineages. The function of HSCs depends upon the signals from surrounding cells found within the highly specialized microenvironment termed the hematopoietic stem cell niche. Understanding and exploiting the HSC niche is a goal of basic scientists and cl...
