Abstract (original English)

Amyotrophic lateral sclerosis (ALS) is a devastating human neurodegenerative disease. The precise pathogenic mechanisms of the disease remain uncertain, and as of yet, there is no effective cure. Human adipose stem cells (hASC) can be easily obtained during operative procedures. hASC have a clinically feasible potential to treat neurodegenerative disorders, since cytosolic extract of hASC contain a number of essential neurotrophic factors. In this study, we investigated effects of hASC extract on the SOD1 G93A mouse model of ALS and in vitro test. Administration of hASC extract improved motor function and prolonged the time until symptom onset, rotarod failure, and death in ALS mice. In the hASC extracts group, choline acetyltransferase immunostaining in the ventral horn of the lumbar spinal cord showed a large number of motor neurons, suggesting normal morphology. The neuroprotective effect of hASC extract in ALS mice was also suggested by western blot analysis of spinal cord extract from ALS mice and in vitro test. hASC extract treatment significantly increased expression of p-Akt, p-CREB, and PGC-1α in SOD1 G93A mouse model and in vitro test. Our results indicated that hASC extract reduced apoptotic cell death and recovered mutant SOD1-induced mitochondrial dysfunction. Moreover, hASC extract reduced mitochondrial membrane potential. In conclusion, we have demonstrated, for
