Amyotrophic lateral sclerosis (ALS) is a lethal disease affecting motoneurons. In familial ALS, patients bear mutations in the superoxide dismutase gene (SOD1). We transplanted human bone marrow mesenchymal stem cells (hMSCs) into the lumbar spinal cord of asymptomatic SOD1(G93A) mice, an experimental model of ALS. hMSCs were found in the spinal cord 10(More)
INTRODUCTION Recently it has been shown in animal models of amyotrophic lateral sclerosis (ALS) that stem cells significantly slow the progression of the disease and prolong survival. We have evaluated the feasibility and safety of a method of intraspinal cord implantation of autologous mesenchymal stem cells (MSCs) in a few well-monitored patients with(More)
Amyotrophic Lateral Sclerosis (ALS) is a devastating incurable disease. Stem-cell-based therapies represent a new possible strategy for ALS clinical research. The objectives of this Phase 1 clinical study were to assess the feasibility and toxicity of mesenchymal stem cell transplantation and to test the impact of a cell therapy in ALS patients. The trial(More)
The enormous plasticity of mesenchymal stem cells (MSCs) suggests an improvement of a standard protocol of isolation and ex vivo expansion for experimental and clinical use. We isolated and expanded MSCs from bone marrow (BM) of pediatric and young adult donors, to analyze the growth kinetic, immunophenotype, telomere length, karyotype during ex vivo(More)
BACKGROUND AND AIMS Mesenchymal stem cells from bone marrow (MSCs) may have the potential to differentiate in vitro and in vivo into hepatocytes. We investigated whether transplanted human MSCs (hMSCs) may engraft the liver of non-obese diabetic severe combined immuno-deficient (NOD/SCID) mice and differentiate into cells of hepatic lineage. METHODS Ex(More)
In this study, we report coexpression of transforming growth factor-beta (TGF-beta) and interleukin-10 (IL-10) in pancreatic carcinoma tissue associated with significantly elevated levels of both cytokines in the sera of pancreatic carcinoma patients. Using conditioned media (CM) of pancreatic carcinoma cells, we further demonstrate that tumor cell-derived(More)
Amyotrophic Lateral Sclerosis is a progressive fatal neurodegenerative disease that targets motor neurons. Its origin is unknown but a main role of reactive astrogliosis and microglia activation in the pathogenesis has been recently demonstrated. Surrounding neurons with healthy adjoining cells completely stops motor neuron death in some cases. Hence stem(More)
OBJECTIVES Our study was aimed to evaluate the feasibility and safety of intraspinal cord implantation of autologous mesenchymal stem cells (MSCs) in a few well-monitored amyotrophic lateral sclerosis (ALS) patients. METHODS Seven patients affected by definite ALS were enrolled in the study and two patients were treated for compassionate use and monitored(More)
OBJECTIVE Mesenchymal stem cells (MSCs) are multipotent cells that can self-renew, proliferate, and exhibit elevated cellular plasticity. To investigate their possible neural fate, we studied human mesenchymal stem cells (hMSCs) in different cell culture conditions from morphological, immunochemical, gene expression, and physiological points of view.
