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...
objective(s):to study the effect of low-frequency vibration on bone marrow stromal cell differentiation and potential bone repair in vivo. materials and methods:forty new zealand rabbits were randomly divided into five groups with eight rabbits in each group. for each group, bone defects were generated in the left humerus of four rabbits, and in the right humerus of the other four rabbits. to t...
In this case report we presented a 37 year-old woman with history of total abdominal hystrectomy, five years ago (1996) due to abnormal uterine bleeding and intrauterine mass, with histopathologic diagnosis of low-grade endometrial stromal sarcoma. There is no history of further adjuvant therapy. Then (five years later) the patient presented with a protruded vaginal mass, and in laparatomy mult...
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): umbilical cord blood-derived mesenchymal stromal cells (ucb-mscs) are ideally suited for use in various cell-based therapies. we investigated a novel induction protocol (nip) to improve the neuronal differentiation of human ucb-mscs under appropriate conditions. materials and methods: this experimental study was performed in iranian blood transfusion organization (ibto), tehran, i...
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...
