We evaluated the beneficial effect of treatment with bone marrow mononuclear cells(BMMC) in a rat model of focal ischemia induced by thermocoagulation of the blood vessels in the left sensorimotor cortex. BMMC were obtained from donor rats and injected into the femoral vein one day after ischemia. BMMC-treated animals received approx. 3×10⁷ cells and(More)
AIMS To assess the safety and feasibility of intra-arterial transplantation of autologous bone marrow mononuclear cells in patients with middle cerebral artery ischemic stroke within 90 days of symptom onset. PATIENTS & METHODS Six patients were included in the study, and they received 1-5 × 10(8) bone marrow mononuclear cell and were evaluated using(More)
Transplantation of autologous bone marrow mononuclear cells (BMMCs) has been proven safe in animal and human studies. However, there are very few studies in stroke patients. In this study, intra-arterial autologous BMMCs were infused in patients with moderate to severe acute middle cerebral artery infarcts. The subjects of this study included 20 patients(More)
P19 cells, a pluripotent cell line derived from a teratocarcinoma induced in C3H/HeHa mice, have been widely used as a model system to study cardiac differentiation. We have used these cells to evaluate the extent to which exposure to DMSO and/or cardiogenol C for 4 days in suspension culture enhanced their differentiation into cardiomyocytes. Cardiac(More)
Brain topography may have its earliest expression as spatial gradients of molecules controlling the deposition of neurones and neuronal processes. In the vertebrate visual system there is evidence that the stereotyped alignment of central retinal projections relies on an initial spatially organized distribution of molecules in both the retina and its(More)
AIMS To assess the biodistribution of bone marrow mononuclear cells (BMMNC) delivered by different routes in patients with subacute middle cerebral artery ischemic stroke. PATIENTS & METHODS This was a nonrandomized, open-label Phase I clinical trial. After bone marrow harvesting, BMMNCs were labeled with technetium-99m and intra-arterially or(More)
There is a need for improved therapies, in terms of utility and effectiveness, for stroke patients; however, over the years, numerous clinical trials of potential drugs have failed to demonstrate positive results. The emerging field of stem cell research has raised several hopes of a therapy for neurological diseases, including stroke. This review discusses(More)
We analyzed the potential input and output components of nitric oxide synthase (NOS)-containing neurons in the rat superior colliculus (SC). To identify whether NOS-positive neurons receive glutamatergic input we investigated the colocalization of NOS with NMDA receptor subunit R1 (NMDAR1). In addition, to examine whether putative nitric oxide synthesizing(More)
We have shown previously that the Jones monoclonal antibody (Jones mAb) recognizes 9-O-acetyl GD3 expressed during periods of neuronal migration and neurite outgrowth in the developing rat nervous system. In the present study we investigated the expression of this ganglioside in the developing cerebellum and correlated this expression with granule cell(More)
The JONES monoclonal antibody has been immunocytochemically associated with regions of the developing rat brain where cell and axon migrations are occurring (Mendez-Otero et al., 1986, 1988). In the present study the antigens recognized by the JONES antibody were analyzed in a variety of brain regions and at developmental ages selected to correspond to the(More)
