Although these genetic-based disorders are generally rare, all together they have a significant impact in the society, with an estimated overall incidence of 1 in 7,663 live births. Currently, there is no cure for leukodystrophies, and the development of effective treatments remains challenging. Not only leukodystrophies generally progress very fast, but also most are multifocal needing the simultaneous targeting at multiple sites. Moreover, as the CNS is affected, the blood\u2013brain barrier (BBB) limits the efficacy of treatment. Recently, interest on cell therapy has increased, and the leukodystrophies for which metabolic correction is needed have become first-choice candidates for cell-based clinical trials. In this review, we present and discuss the available cell transplantation therapies in metabolic leukodystrophies including fucosidosis, X-linked adrenoleukodystrophy, metachromatic leukodystrophy, Canavan disease, and Krabbe's disease. We will discuss the latest advances of cell therapy and its pitfalls in this group of disorders, taking into account, among others, the limitations imposed by reduced cell migration in multifocal conditions, the need to achieve corrective enzyme threshold levels, and the growing awareness that not only myelin but also the associated axonopathy needs to be targeted in some leukodystrophies.<\/jats:p>","DOI":"10.3727\/096368912x656117","type":"journal-article","created":{"date-parts":[[2013,2,23]],"date-time":"2013-02-23T09:16:59Z","timestamp":1361611019000},"page":"189-204","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":19,"title":["Advances and Pitfalls of Cell Therapy in Metabolic Leukodystrophies"],"prefix":"10.1177","volume":"22","author":[{"given":"Catarina Oliveira","family":"Miranda","sequence":"first","affiliation":[{"name":"Nerve Regeneration Group, IBMC-Instituto de Biologia Molecular e Celular, Porto, Portugal"},{"name":"ICBAS, Universidade do Porto, Porto, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pedro","family":"Brites","sequence":"additional","affiliation":[{"name":"Nerve Regeneration Group, IBMC-Instituto de Biologia Molecular e Celular, Porto, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M\u00f3nica Mendes","family":"Sousa","sequence":"additional","affiliation":[{"name":"Nerve Regeneration Group, IBMC-Instituto de Biologia Molecular e Celular, Porto, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Carla Andreia","family":"Teixeira","sequence":"additional","affiliation":[{"name":"Nerve Regeneration Group, IBMC-Instituto de Biologia Molecular e Celular, Porto, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2013,2,1]]},"reference":[{"key":"bibr1-096368912X656117","doi-asserted-by":"publisher","DOI":"10.1182\/blood-2004-04-1559"},{"key":"bibr2-096368912X656117","doi-asserted-by":"publisher","DOI":"10.1016\/j.jfms.2010.09.001"},{"issue":"1","key":"bibr3-096368912X656117","doi-asserted-by":"crossref","first-page":"33","DOI":"10.1002\/iub.284","volume":"62","author":"Beck M.","year":"2010","journal-title":"IUBMB Life"},{"key":"bibr4-096368912X656117","doi-asserted-by":"publisher","DOI":"10.1097\/00019052-200106000-00007"},{"key":"bibr5-096368912X656117","doi-asserted-by":"publisher","DOI":"10.1172\/JCI28873"},{"key":"bibr6-096368912X656117","doi-asserted-by":"publisher","DOI":"10.1172\/JCI200419205"},{"key":"bibr7-096368912X656117","doi-asserted-by":"publisher","DOI":"10.1016\/S0304-3940(03)00633-5"},{"key":"bibr8-096368912X656117","doi-asserted-by":"publisher","DOI":"10.1212\/WNL.0b013e3181eee46b"},{"key":"bibr9-096368912X656117","doi-asserted-by":"publisher","DOI":"10.1111\/j.1750-3639.2010.00394.x"},{"key":"bibr10-096368912X656117","doi-asserted-by":"publisher","DOI":"10.1126\/science.1171242"},{"key":"bibr11-096368912X656117","doi-asserted-by":"publisher","DOI":"10.1007\/s00401-011-0814-2"},{"key":"bibr12-096368912X656117","doi-asserted-by":"publisher","DOI":"10.1634\/stemcells.2007-0197"},{"key":"bibr13-096368912X656117","doi-asserted-by":"publisher","DOI":"10.1517\/14712590802573395"},{"key":"bibr14-096368912X656117","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2184.2008.00559.x"},{"key":"bibr15-096368912X656117","doi-asserted-by":"publisher","DOI":"10.1016\/j.expneurol.2005.10.029"},{"key":"bibr16-096368912X656117","doi-asserted-by":"publisher","DOI":"10.1016\/j.pediatrneurol.2008.11.010"},{"key":"bibr17-096368912X656117","doi-asserted-by":"publisher","DOI":"10.1097\/GIM.0b013e3181a16e04"},{"key":"bibr18-096368912X656117","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.94.8.4080"},{"key":"bibr19-096368912X656117","doi-asserted-by":"publisher","DOI":"10.1542\/peds.2006-0747"},{"key":"bibr20-096368912X656117","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMoa042604"},{"key":"bibr21-096368912X656117","doi-asserted-by":"publisher","DOI":"10.1172\/JCI117363"},{"key":"bibr22-096368912X656117","doi-asserted-by":"publisher","DOI":"10.1586\/ern.10.127"},{"key":"bibr23-096368912X656117","doi-asserted-by":"publisher","DOI":"10.1016\/S0960-8966(97)00060-6"},{"issue":"5","key":"bibr24-096368912X656117","first-page":"2282","volume":"24","author":"Ferrara M.
