Abstract (original English)
Deterioration in muscle mass, strength, and physical performance due to conditions such as sarcopenia can affect daily activities and quality of life in the elderly. Exercise and mesenchymal stem cells (MSCs) are potential therapies for sarcopenia. This study evaluates the combined effects of exercise and adipose-derived MSCs (ADMSCs) in aged rats with sarcopenia. Eighteen-month-old rats were randomly divided into four groups: control, exercise (Ex), ADMSCs injection (MSC), and ADMSCs injection with exercise (MSC + Ex). Gastrocnemius (GCM) muscle mass increased in the Ex, MSC, and MSC + Ex groups compared to the control group. Although the mean CSA did not differ significantly between the groups, the size distribution of myofibers shifted toward larger sizes in the Ex and MSC + Ex groups. The MSC + Ex group performed best in functional tests, including the rotarod and hot plate tests. The protein expression levels of tumor necrosis factor (TNF) and the p-AMP-activated protein kinase (AMPK)/AMPK ratio in the GCM muscle were the lowest in the MSC + Ex group. This study demonstrates that combining exercise and ADMSC interventions was the most effective treatment for aged sarcopenic rats, suggesting a potential synergistic approach for sarcopenia treatment.
