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...
UNLABELLED Several bone-seeking radionuclides (32P, 89Sr, 186Re, and 153Sm) have been used to treat bone pain. The limiting factor in this modality is marrow toxicity. Our hypothesis is that marrow toxicity can be reduced while maintaining therapeutic efficacy using radionuclides that emit short-range beta particles or conversion electrons (CEs). A recent study on 47 patients using the short-ra...
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...
since bone marrow has been shown to contain osteoprogenitor cells, an experiment was devised to test its effects when injected percutaneously into osteotomies sites in rabbit radii. in this experimental study, the osteogenicity and its effect on early bone repair of bone marrow grafts were investigated. the purpose of this study was to determine whether bone marrow grafted percutaneously led to...
بررسی علل شیوع پان سیتوپنی در میان بیماران بستری بخش خون بیمارستان 501 ارتش بین سال های 1373 تا 1381
Background and Aim: Pancytopenia is the reduction of all 3 series of blood cells e.g. Erythroids, leukocytes, and platelets. The causes of pancytopenia are diverse. Some are related to bone marrow failure caused by toxins (Bone Marrow with no cells or low cells). Bone marrow may be infiltrated by malignant and foreign cells or bone marrow fibrosis. Genetics factor and geographical disease could...
background: the present study investigated the functional maturity of oligodendrocyte derived from rat bone marrow stromal cells (bmsc). methods: the bmsc were isolated from female sprague-dawley rats and evaluated for different markers, such as fibronectin, cd106, cd90, oct-4 and cd45. transdifferentiation of olc from bmsc was obtained by exposing the bmsc to dmso and 1 µm all-trans-retinoic a...
background: recent reports demonstrated that intravenous route as a minimally invasive method, similar to direct injection, is suitable for bone marrow stromal cell (bmsc) transplantation. in this study, we made a comparison of intraspinal and intravenous route of bmsc administration to repair injured spinal cord tissue. methods: six groups of adult female rats were used in this study. laminect...
introduction demyelination is a common lesion of spinal cord injury; cell therapy is an approach for replacing the lost oligodendrocytes. objective in this study, bone marrow stromal cells (bmscs) have been transdifferentiated into oligodendrocyte-like cells (olcs) and used in cytotherapy of contused spinal cords in rats. materials and methods the bmscs were collected from rat long bones, cultu...
objective(s): intracerebral injection of bone marrow stromal cells (bmscs) is being investigated as a therapeutic tool to prevent alzheimer's disease (ad). our aim was to investigate the effects of bmscs by intrathecal injection in ad rat model. materials and methods: bmscs were obtained from the bone marrow of wistar rat and transplanted into ad rat model via intrathecal injection. the ra...
objective(s): bone marrow-derived mesenchymal stem cells (bm-mscs) potentials make them appropriate for cell therapy including ability of differentiation and release of anti-inflammatory cytokines and growth factors secreta. for treatment of azoospermia to induce proliferation and differentiation of germ cells, mscs transplantation has been introduced. the aim of the present experimental case-c...
