Stem cell-based treatment is a promising frontier for neurodegenerative diseases. We propose a novel protocol for inducing the differentiation of rat mesenchymal stem cells (MSCs) toward neurotrophic factor (NTF)-secreting cells as a possible neuroprotective agent. One of the major caveats of stem cell transplantation is their fate post-transplantation. To(More)
Stem cell-based regenerative medicine raises great hope for the treatment of multiple sclerosis (MS). Bone marrow-derived mesenchymal stem cells (BM-MSCs) are being tested in clinical trials. Bone marrow is the traditional source of human MSCs, but human term placenta appears to be an excellent alternative because of its availability, without ethical(More)
Stem cell-based regenerative therapy is considered a promising cellular therapeutic approach for the patients with incurable brain diseases. Mesenchymal stem cells (MSCs) represent an attractive cell source for regenerative medicine strategies for the treatment of the diseased brain. Previous studies have shown that these cells improve behavioral deficits(More)
Quinolinic acid (QA) induced striatal lesion is an important model for excitotoxicity that is also used for efficacy studies. To date, the morphological and spectroscopic indices of this model have not been studied longitudinally by MRI; therefore the objectives of this study were aimed at following the lesion progression and changes in N-acetyl aspartate(More)
We hypothesized that injection of anti-basal antibodies from patients with Sydenham’s chorea into rats’ striatum will induce behavioral and histological changes. Antibodies from eight Sydenham’s chorea patients and eight age-matched controls were injected into the left caudate of 16 rats. Apomorphine- and amphetamine-induced rotations were performed on days(More)
Stem cell-based treatment for Huntington's disease (HD) is an expanding field of research. Although various stem cells have been shown to be beneficial in vivo, no long standing clinical effect has been demonstrated. To address this issue, we are developing a stem cell-based therapy designed to improve the microenvironment of the diseased tissue via(More)
Stem cell-based therapy is a promising treatment for neurodegenerative diseases. In our laboratory, a novel protocol has been developed to induce bone marrow-derived mesenchymal stem cells (MSC) into neurotrophic factors- secreting cells (NTF-SC), thus combining stem cell-based therapy with the NTF-based neuroprotection. These cells produce and secrete(More)
PURPOSE To evaluate the neuroprotective effect of intravitreal injections of neurotrophic factors secreting mesenchymal stem cells (NTF-SCs) on the survival of retinal ganglion cells (RGCs) in rat eyes after optic nerve transection (ONT). METHODS Rat and human bone marrow-derived mesenchymal stem cells (MSCs) were induced to secrete high levels of NTF.(More)
Sciatic nerve injury is common and may cause neurological deficits. Previous studies showed that administration of neurotrophic factors (NTFs), naturally occurring proteins that support the development and survival of neurons, preserved and protected damaged motor neuron in the injured sciatic nerve. We have been successful in converting bone marrow-derived(More)
Huntington's disease (HD) is a hereditary, progressive and ultimately fatal neurodegenerative disorder. Excitotoxicity and reduced availability of neurotrophic factors (NTFs) likely play roles in HD pathogenesis. Recently we developed a protocol that induces adult human bone marrow derived mesenchymal stem cells (MSCs) into becoming NTF secreting cells(More)
