ABSTRACT

OBJECTIVE:

This study aimed to investigate the protective effect of bone marrow mesenchymal stem cell-derived exosomes (BMSCs-exo) against lower limb ischemia/reperfusion (I/R) injury-induced pyroptosis in skeletal muscle.

METHODS:

A mouse model of lower limb I/R injury was utilized to assess the impact of BMSCs-exo, particularly when loaded with microRNA-367-3p (miR-367-3p), on pyroptosis. Histological examination, wet weight/dry weight ratio measurements, and luciferase assays were employed to elucidate the mechanisms involved. KEY

FINDINGS:

BMSCs-exo effectively suppressed pyroptosis in injured skeletal muscle tissue. Loading BMSCs-exo with miR-367-3p enhanced this protective effect by downregulating key pyroptosis-related proteins. Luciferase assays identified enhancer of zeste homolog 2 (EZH2) as a direct target of miR-367-3p in BMSCs-exo.

CONCLUSIONS:

BMSCs-exo loaded with miR-367-3p safeguarded mouse skeletal muscle against pyroptosis-induced I/R injury by targeting EZH2. These findings offer valuable insights into potential therapeutic strategies for lower limb I/R injuries, emphasizing the therapeutic potential of BMSCs-exo in mitigating tissue damage caused by pyroptosis.
