background: during the resent years there has been interest in using bone marrow stem cells to treat liver cirrhosis. however, there is a potential concern for malignant transformation after stem cell therapy. the aim of this study was to evaluate the development of hepatocellular carcinoma (hcc) after autologous bone marrow stem cell transplantation for liver cirrhosis. methods: all the patien...

isolated extramedullary relapse of chronic myelogenous leukemia (cml) after allogeneic stem cell transplant is rare. there is a case report of a child who developed a granulocytic sarcoma of the maxillary and sphenoid sinuses and lumbosacral spinal cord mass 18 months after allogeneic bone marrow transplant for cml. he was presented with per orbital edema and neurological deficit of lower extre...

Background:  Renal transplantation is the best choose in the end stage renal disease (ESRD), and acute rejection and graft dysfunction remain major challenges in the worldwide, even with the advent of new immunosuppressive drugs. The novel cell-based anti-rejection treatments have been studied by using different stem cell sources. In this study, transplantation of autologous-bone-marrow-derive...

background: the aim of this study was optimization of the polyfect gene delivery method of pcdna3.1 expression vector transfected with the mouse pdx-1 gene in three different kinds of mesenchymal stem cells and hepa cells as well as comparison of transfection efficiency leading to expression of the mentioned gene in the cell types used. materials and methods: rat bone marrow-derived mesenchymal...

We recently reported that a DNA plasmid coding p62-SQSTM1 acts as an effective anti tumor vaccine against both transplantable mouse tumors and canine spontaneous mammary neoplasms. Here we report the unexpected finding that intramuscular delivery of p62 DNA exerts a powerful anti-osteoporotic activity in a mouse model of inflammatory bone loss (i.e, ovariectomy) by combining bone-sparing and os...

background: there are multiple methods for acceleration of bone healing. bone marrow has been shown to contain osteoprogenitor cells.   objective: to determine the effect of percutaneous bone marrow injection on bone healing.   methods: 15 mature, 2-kg-weighing white new zealand rabbits from both sexes were randomized into 3 groups: group i: only osteotomy of right radius was performed and a 5 ...

the effectiveness of an intervention against cancer cells compared to normal tissue. Although chemotherapy and radiation are common and effective treatment modalities for skeletal neoplasia (1), bone-seeking radioisotopes offer a new opportunity to provide additional benefit via specific targeting of the skeleton and/or bone-forming lesions (e.g. osteoblastic metastases in the skeleton, marrow,...

Background: Hematological abnormalities are a common complication of HIV infection and occur in all stages of the infection. These abnormalities increase as the disease advances. We aimed to evaluate the diagnostic utility of bone marrow sampling in HIV-positive patients. Methods: 40 HIV-infected individuals were screened for hematological abnormalities. Investigations such as iron studies, he...
