Without treatment, the resulting GAG accumulation causes multisystem dysfunction and death within the first decade. Current treatments include allogeneic hematopoietic stem cell transplantation (HSCT) and enzyme replacement therapy. HSCT ameliorates clinical features and extends life but is not available to all patients, and inadequately corrects the most devastating features of the disease including mental retardation and skeletal deformities. Recent developments suggest that stem cells can be used to deliver needed enzymes to the central nervous system. To test this concept, we transplanted bone marrow-derived normal adult human MultiStem\u00ae cells into the cerebral lateral ventricles of immunodeficient MPS-I neonatal mice. Transplanted cells and human-specific DNA were detected in the hippocampal formation, striatum, and other areas of the central nervous system. Brain tissue assays revealed significant long-term decrease in GAG levels in the hippocampus and striatum. Sensorimotor testing 6 months after transplantation demonstrated significantly improved rotarod performance of transplanted mice in comparison to nontransplanted and sham-transplanted control animals. These results suggest that a single injection of MultiStem cells into the cerebral ventricles of neonatal MPS-I mice induces sustained reduction in GAG accumulation within the brain, and modest long-term improvement in sensorimotor function.<\/jats:p>","DOI":"10.3727\/096368912x636894","type":"journal-article","created":{"date-parts":[[2012,4,4]],"date-time":"2012-04-04T14:00:30Z","timestamp":1333548030000},"page":"1577-1593","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":8,"title":["Intracerebroventricular Transplantation of Human Bone Marrow-Derived Multipotent Progenitor Cells in an Immunodeficient Mouse Model of Mucopolysaccharidosis Type I (MPS-I)"],"prefix":"10.1177","volume":"21","author":[{"given":"Zhenhong","family":"Nan","sequence":"first","affiliation":[{"name":"Department of Neurosurgery, University of Minnesota, Minneapolis, MN, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Laurie","family":"Shekels","sequence":"additional","affiliation":[{"name":"Hematology-Oncology Section, VA Medical Center, Minneapolis, MN, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Oleg","family":"Ryabinin","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, University of Minnesota, Minneapolis, MN, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Carrie","family":"Evavold","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, University of Minnesota, Minneapolis, MN, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Matthew S.","family":"Nelson","sequence":"additional","affiliation":[{"name":"Hematology-Oncology Section, VA Medical Center, Minneapolis, MN, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shaukat A.","family":"Khan","sequence":"additional","affiliation":[{"name":"Hematology-Oncology Section, VA Medical Center, Minneapolis, MN, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Robert J.","family":"Deans","sequence":"additional","affiliation":[{"name":"Athersys Inc., Cleveland, OH, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Robert W.","family":"Mays","sequence":"additional","affiliation":[{"name":"Athersys Inc., Cleveland, OH, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Walter C.","family":"Low","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, University of Minnesota, Minneapolis, MN, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pankaj","family":"Gupta","sequence":"additional","affiliation":[{"name":"Hematology-Oncology Section, VA Medical Center, Minneapolis, MN, USA"},{"name":"Hematology-Oncology-Transplantation Division, Department of Medicine, University of Minnesota, Minneapolis, MN, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2012,7,1]]},"reference":[{"key":"bibr1-096368912X636894","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0007809"},{"issue":"2","key":"bibr2-096368912X636894","first-page":"505","volume":"118","author":"Aranguren X.
