There are two main categories for stem cells a cording to their origin: Embryonic Stem Cells and Adult Stem Cell. Mesenchymal stem cell, supporting hematopoetic stem cells in bone marrow, can regenerate tissues such as bone, cartilage, muscle, tendon and fatty tissue. These cells were recognized for the first time by Friedenstein and Petrokova who could isolate theme from rat bone marrow.Mesenc...
Leukemia is the most common childhood cancer and accounts for 30-40% of all malignancies. A retrospective review was performed of the hospital records of 9 children, 6 boys and 3 girls, aged from 2.5 to 15 years with ALL initially referred to Nemazee hospital Nuclear medicine center for whole body bone scanning between 2000 and 2002. Bone marrow pathology established ALL (L1) in two and ALL (...

background infertility is a serious social problem in advanced nations, with male factor in half of all cases of infertility. this study was conducted to determine the regenerative effect of bone marrow-derived stem cells in spermatogenesis of infertile hamster. methods twelve adult male hamsters were equally divided into azoospermic and control groups. busulfan was intraperitoneally used for i...
adenoviruses are recognized as common human pathogens that are responsible for a wide variety of infectious syndromes. bone marrow transplant patients are prone to life threatening opportunistic infections like adenoviruses. the nested polymerase chain reaction has provided an alternative, sensitive diagnostic method for detection of adenoviruses. in this study we developed pcr from hexon genes...
objective(s):the application of stem cells holds great promises in cell transplants. considering the lack of optimal in vitro model for hepatogenic differentiation, this study was designed to examine the effects of laminin matrix on the improvement of in vitro differentiation of human bone marrow mesenchymal stem cells (hbm-msc) into the more functional hepatocyte-like cells. materials and meth...
Currently several studies are being carried out on various properties of mesenchymal stem cells (MSCs)however there are a few investigations about drug metabolizing properties of these cells. The aim of thisstudy was to measure the key factors involved in drug metabolism in human bone marrow MSCs. For thispurpose, cellular glutathione (GSH), glutathione Stransferase (GSTs) and...
Bone Marrow Edema Syndrome (BMES) is an uncommon, self-limited and with unknown etiology characterized by severe pain with no history of trauma. Due to low prevalence of BMES and its non-specific signs, correct diagnosis is often delayed intensifying bone pain and impairing patients’ function and quality of life. In this study we treated a patient with bone marrow edema syndrome in right a...
Objective- To evaluate the role of autogenous bone marrow (BM), in the healing of experimentally induced burn wound in rats. Design- Experimental in-vivo study. Animals- 20 adult male white New Zealand rabbits. Procedures- Two burn wounds were created under general anesthesia using a 100 W electric soldering iron, heated to the point of redness (about 800° C) on each side of the back, 4...
Background: Recently, bone-marrow-derived cells have introduced new therapeutic approaches to the management of wound healing in severe skin injuries. Bone marrow-derived stromal cells are described as a heterogeneous population, including mesenchymal stem cells, hematopoietic stem cells, and fibro-blast cells. Results derived from several studies indicate that these cells may contribute to tis...
