Stem cells, which resemble white blood cells with very small nuclei and cytoplasm, have the capacity to differentiate into any of the mature blood cells. Very primitive, pleuripotent stem cells have the capability of differentiation into other cell types, such as heart and nerve, as well. Since 1968, stem cells in bone marrow have been used in treatment of leukemias, lymphomas, and immune defic...
objective(s) arsenic compounds are potent human carcinogen and produce a variety of stress responses in mammalian cells. recently sodium arsenite has been recommended to be used as anti malignancy drug by american food and drug administration (fda). in this study, we aimed to determine the apoptosis inducing effect of sodium arsenite on rat bone marrow mesenchymal stem cells exposed in vitro. m...
Background: MSCs have been isolated from a variety of mammals by the plastic adherence method. However, this method can be problematic due to the unwanted growth of hematopoietic cells and non-MSCs. The potential of MSCs to differentiate along multiple lineages is the key to the identification of stem cell populations in the absence of molecular markers. In the present study, we describe a homo...
BACKGROUND In vivo tissue regeneration depends on migration of stem cells into injured areas, their differentiation into specific cell types, and their interaction with other cells that are necessary to generate new tissue. Human mesenchymal stem cells, a subset of bone marrow stromal cells (BMSCs), can migrate and differentiate into osteoblasts in bone tissue. This can be facilitated by recomb...
Bone marrow mesenchymal stem cells can differentiate into neurons and astrocytes after transplantation in the spinal cord of rats with ischemia/reperfusion injury. Although bone marrow mesenchymal stem cells are known to protect against spinal cord ischemia/reperfusion injury through anti-apoptotic effects, the precise mechanisms remain unclear. In the present study, bone marrow mesenchymal ste...
Previous work has shown failure of engraftment in lethally irradiated dogs when autologous marrow was depleted of Ia-positive cells with an anti-Ia antibody and complement before infusion. In the current study, we have utilized an avidin-biotin immunoadsorption procedure to obtain a population of highly enriched Ia-positive cells for autologous bone marrow transplantation in dogs given lethal i...
introduction: there are the evidences to suggest that bone marrow stromal cells (bmscs) not only differentiate into mesodermal cells, but also adopt the fate of endodermal and ectodermal cell types. bmscs can be a valuable cell source as an autograph for clinical application involving regeneration of the central nervous system. bone marrow stromal cells can be expanded rapidly in vitro and have...
in this issue of irjo movassat et al1 (p: 33-38) present a case series of leber's congenital amaurosis (lca). lca is the most severe form of inherited retinal dystrophy responsible for congenital blindness with an early age of onset and accounts for at least 5% of all inherited retinal diseases which affect about one in 3500 individuals in the world. usually degenerative anomalies of the r...
Bone repair requires the mobilization of adult skeletal stem cells/progenitors to allow deposition of cartilage and bone at the injury site. These stem cells/progenitors are believed to come from multiple sources including the bone marrow and the periosteum. The goal of this study was to establish the cellular contributions of bone marrow and periosteum to bone healing in vivo and to assess the...
The stem cells that maintain and repair the postnatal skeleton remain undefined. One model suggests that perisinusoidal mesenchymal stem cells (MSCs) give rise to osteoblasts, chondrocytes, marrow stromal cells, and adipocytes, although the existence of these cells has not been proven through fate-mapping experiments. We demonstrate here that expression of the bone morphogenetic protein (BMP) a...
