There is currently very limited effective pharmacological treatment for amyotrophic lateral sclerosis. Recent evidence suggests that Adipose-derived Stem Cell Conditioned Media (ASC-CM) have strong anti-oxidative and anti-neuronal death properties; thus, the present study tested the effects of ASC-CM in mice expressing a mutant superoxide dismutase (SOD1G93A) linked to human amyotrophic lateral sclerosis. Administration of ASC-CM after symptom onset significantly increased the lifespan of SOD1G93Amice by approximately 2 weeks, nearly doubling post-onset survival. Moreover, immunohistochemical analysis detected less activation of microglia and astrocytes and higher motor neuron counts at an early symptomatic stage (7 days following onset) in the spinal cords of SOD1G93Amice given ASC-CM treatment. Additionally, lower levels of phosphorylated p38, a mitogen-activated protein kinase that is involved in both inflammation and neuronal death, were observed in the spinal cords of SOD1G93A mice treated with ASC-CM for 3 and 7days. These results indicate that ASC-CM may represent a novel and effective therapeutic for the treatment of amyotrophic lateral sclerosis and these significant neuroprotective effects observed in a commonly used amyotrophic lateral sclerosis mouse model validate the therapeutic potential of ASC-CM for slowing disease progression by attenuating the neuroinflammation and motor neuron cell death associated with clinical amyotrophic lateral sclerosis pathology.
