Background: Preclinical studies suggest that stem cells may be a valuable therapeutic tool in amyotrophic lateral sclerosis (ALS). As it has been demonstrated that there are molecular changes at the end-plate during the early stages of motorneuron degeneration in animal models, we hypothesize that the local effect of this stem cell delivery method could slow the progressive loss of motor units (MUs) in ALS patients.
Methods: We designed a Phase I/II clinical trial to study the safety of intramuscularly implanting autologous bone marrow mononuclear cells (BMMCs), including stem cells, in ALS patients and their possible effects on the MU of the tibialis anterior (TA) muscle.
Multiple myeloma (MM) remains as an incurable disease and, although allogeneic hematopoietic stem cell transplantation (allo-HSCT) is a potentially curative approach, most patients ultimately relapse, and their treatment remains challenging. Because allo-HSCT can modify not only the biology of the disease, but also the immune system and the microenvironment, it can potentially enhance the response to rescue therapies. Information on the efficacy and safety of novel drugs in patients relapsing after allo-HSCT is lacking, however.

Methods: Stem cells were surgically injected in the spinal cord of 11 spinal-onset amyotrophic lateral sclerosis patients (group 1); 21 matched patients were the control group (group 2), comprising ALS patients with an intrathecal saline infusion. Single-voxel 1.
The safety of autologous bone marrow mononuclear cells (ABMNC) intraspinal infusion in amyotrophic lateral sclerosis (ALS) patients was evaluated considering breathing and sleep patterns. Patients between 20 and 65 years old were eligible if they had definite ALS, spinal onset, a disease duration between 6 and 36 months, FVC>50%, and a below 90% oxygen saturation (T90) <2% of sleep time. The transplant was performed 6 months after enrollment.
