BACKGROUND Mesenchymal stem cells (MSCs) represent a potential useful source for cell-based glioma therapies because these cells evidence both orthodox and unorthodox plasticity and also show tropism for cancer. In this study, the authors attempted to access the cytotoxicity of human umbilical cord blood (hUCB)-derived MSCs, with or without cytokine(More)
Brain-derived neurotrophic factor (BDNF) plays an important role in the differentiation, development, and survival of neural stem cells. In this study, we analyzed its effects on the stimulation of human umbilical cord blood-derived mesenchymal stem cells in terms of their potential to differentiate into neuron-like cells, their survival characteristics,(More)
Numerous studies have reported that mesenchymal stem cells (MSCs) can ameliorate neurological deficits in ischemic stroke models. Among the various hypotheses that have been suggested to explain the therapeutic mechanism underlying these observations, neurogenesis is thought to be critical. To enhance the therapeutic benefits of human bone marrow-derived(More)
INTRODUCTION Stem cell transplantation is a promising therapeutic strategy for the treatment of stroke. Mesenchymal stem cells (MSCs) are a potential cell source for clinical application because they can be easily obtained and cultivated with a high proliferative capacity. The safety and efficacy of cell therapy depends on the mode of cell administration.(More)
Numerous studies have shown the benefits of mesenchymal stem cells (MSCs) on the repair of spinal cord injury (SCI) model and on behavioral improvement, but the underlying mechanisms remain unclear. In this study, to investigate possible mechanisms by which MSCs contribute to the alleviation of neurologic deficits, we examined the potential effect of human(More)
Multiple sclerosis (MS) is the most common inflammatory demyelinating disorder of the central nervous system (CNS). Minocycline ameliorates the clinical severity of MS and exhibits antiinflammatory, neuroprotective activities, and good tolerance for long-term use, whereas it is toxic to the CNS. Recently, the immunomodulation and neuroprotection(More)
Temozolomide (TMZ) has become a key therapeutic agent in patients with malignant gliomas; however, its survival benefit remains unsatisfactory. Valproic acid (VPA) has emerged as an anticancer drug via inhibition of histone deacetylases (HDACs), but the therapeutic advantages of a combination with VPA and TMZ remain poorly understood. The main aim of the(More)
Interferon-beta (IFN- β ), a well-established standard treatment for multiple sclerosis (MS), has proved to exhibit clinical efficacy. In this study, we first evaluated the therapeutic effects for MS using human bone marrow-derived mesenchymal stem cells (hBM-MSCs) as delivery vehicles with lesion-targeting capability and IFN- β as therapeutic gene. We also(More)
Mounting evidence suggests that lipoxygenase (LO)-catalyzed products may play a key role in the development and progression of human cancers. In this study, we analyzed the effects of a 5-LO inhibitor, which inhibits the conversion of arachidonic acid to leukotrienes, on cell proliferation and apoptosis in human malignant glioma cells, including(More)
Bone marrow stromal cells (BMSC) exhibit many traits of a stem cell population. Knowing that BMSC have the ability to self-renew, proliferate and differentiate into a variety of cell types, questions may arise as to whether these traits differ between the cells that have different expansion times. In this study, we examined the stem cell potentiality of(More)
