Title: A Phase I/II, Open Label Study to Evaluate Safety, Tolerability and Therapeutic Effects of Transplantation of Autologous Cultured Mesenchymal Bone Marrow Stromal Cells Secreting Neurotrophic Factors (MSC-NTF), in ALS Patients.
Brief Summary: The study will evaluate the safety, tolerability and therapeutic effects (preliminary efficacy) of injection of autologous cultured mesenchymal bone marrow stromal cells secreting neurotrophic factors (MSC-NTF), as a possible treatment for patients with Amyotrophic Lateral Sclerosis (ALS) at the early and progressive disease stages.
