چکیده

There is increasing evidence that the transplanted BMSC significantly promote functional recovery after CNS damage in the animal models of various kinds of CNS disorders, including cerebral infarct, traumatic brain injury and spinal cord injury. However, there are several shortages of information when considering clinical application of BMSC transplantation for patients with CNS disorders. In this review, therefore, we discuss what we should clarify to establish cell transplantation therapy as the scientifically proven entity in clinical situation and describe our recent works for this purpose. The BMSC have the ability to alter their gene expression profile and phenotype in response to the surrounding circumstances and to protect the neurons by producing some neurotrophic factors. They also promote neurite extension and rebuild the neural circuits in the injured CNS. The BMSC can be expanded in vitro using the animal serum-free medium. Pharmacological modulation may accelerate the in vitro proliferation of the BMSC. Using in vivo optical imaging technique, the transplanted BMSC can non-invasively be tracked in the living animals for at least 8 weeks after transplantation. It is urgent issues to develop clinical imaging technique to track the transplanted cells in the CNS and evaluate the therapeutic significance of BMSC transplantation in order to establish it as a definite therapeutic strategy in clinical situation in the future.

Bone marrow stromal cells and their application in neural injuries

Background: This article reviews experimental and clinical studies in which neural injuries repaired with bone marrow stromal cells. History: Bone marrow contains two kinds of stem cells: hematopoietic and nonhematopoietic (stromal) stem cell. In vitro studies indicate that bone marrow stromal cells have the capacity of differentiation into other cells (such as neural cell) under treatment wit...

Role of Stem Cell Transplantation in the Treatment of Burkitt Lymphoma; A Systematic Review

Background: Burkitt lymphoma is a common subtype of non-Hodgkin lymphoma in children. It has a rapid and aggressive clinical course with frequent involvement of bone marrow and central nervous system. Systemic chemotherapy is the mainstay of the treatment for this malignancy in children. In this systematic review, we discuss autologous and allogeneic hematopoietic stem cell transplantation (HSC...

Comparison of Transplantation of Bone Marrow Stromal Cells (BMSC) and Stem Cell Mobilization by Granulocyte Colony Stimulating Factor after Traumatic Brain Injury in Rat

Background: Recent clinical studies of treating traumatic brain injury (TBI) with autologous adult stem cells led us to compare effect of intravenous injection of bone marrow mesenchymal stem cells (BMSC) and bone marrow hematopoietic stem cell mobilization, induced by granulocyte colony stimulating factor (G-CSF), in rats with a cortical compact device. Methods: Forty adult male Wistar rats w...

Harvesting of bone marrow mesenchymal stem cells from live rats and the in vitro differentiation of bone marrow mesenchymal stem cells into neuron-like cells

In the bone marrow, there are certain populations of stem cell sources with the capacity to differentiate into several different types of cells. Ideally, cell transplants would be readily obtainable, easy to expand and bank, and capable of surviving for sufficient periods of time. Bone marrow mesenchymal stem cells (BM-MSCs) possess all of these characteristics. One of the most important benefi...
