The use of adult stem cells for cell-based tissue engineering and regeneration strategies represents a promising approach for skeletal muscle repair. We have evaluated the combination of adipose tissue-derived adult stem cells (ADSCs) obtained from autologous liposuction and injectable poly(lactic-co-glycolic acid) (PLGA) spheres for muscle regeneration. ADSCs attached to PLGA spheres and PLGA spheres alone were cultured in myogenic medium for 21 days and injected subcutaneously into the necks of nude mice. After 30 and 60 days, the mice were sacrificed, and newly formed tissues were analyzed by immunostaining, H and E staining, and RT-PCR. We found that ADSCs attached to PLGA spheres, but not PLGA spheres alone, were able to generate muscle tissue. These findings suggest that ADSCs and PLGA spheres are useful materials for muscle tissue engineering and that their combination can be used in clinical settings for muscle regeneration.
