Human Multipotent Stromal Cells (MSCs) Increase Neurogenesis and Decrease Atrophy of the Striatum in a Transgenic Mouse Model for Huntington’s Disease 1,3 1 3 1,2 Brooke R. Snyder , Andrew M. Chiu , Darwin J. Prockop *, Anthony W. S. Chan * 1 Yerkes National Primate Research Center, Atlanta, Georgia, United States of America, 2 Department of Human Genetics, Emory University School of Medicine, Atlanta, Georgia, United States of America, 3 Center for Gene Therapy, Tulane University Health Science Center, New Orleans, Louisiana, United States of America Abstract Background: Implantation of human multipotent stromal cells from bone marrow (hMSCs) into the dentate gyrus of the hippocampus of mice was previously shown to stimulate proliferation, migration and neural differentiation of endogenous neural stem cells. We hypothesized that hMSCs would be beneficial in a mouse model of Huntington disease (HD) due to these neurogenic effects. Results: We implanted hMSCs into the striatum of transgenic mice (N171-82Q) that are a model for HD. The implanted hMSCs rapidly disappeared over 3 to 15 days. However, they increased proliferation and neural differentiation of endogenous neural stem cells for up to 30 days. They also increased neurotrophic signaling and decreased atrophy of the striatum in 3-month old HD mice implanted with hMSCs one month earlier. Conclusions: The results therefore suggested that neural implantation of hMSCs may be of benefit in HD but a number of parameters of dose, treatment schedule, and route of administration need to be optimized.
