This multi-center, randomized, double blind, placebo controlled study will evaluate the safety and efficacy of a single combined intramuscular and intrathecal administration of MSC-NTF cells in early-stage ALS patients. Patients will be followed for approximately three months before transplantation with their autologous MSC-NTF cells or placebo. During this period of time, patient bone-marrow will be harvested and mesenchymal stromal cells will be isolated and expanded. Following treatment patients will be followed for a total of six months at monthly visits.
