Plain-English summary
A 6-year-old Dutch Warmblood gelding was diagnosed with a suspensory ligament injury, which is a common cause of lameness in athletic horses. To help heal the injury, veterinarians injected microvesicles derived from rejuvenated stem cells treated with a combination of 5-azacytidine and resveratrol. This treatment led to improved healing in the injured ligament, including better tissue filling and increased blood flow. The horse showed positive results, suggesting that this approach could be a promising alternative to traditional stem cell therapies for similar injuries.

Abstract
BACKGROUND: In athlete horses, suspensory ligament (SL) injuries are the most common cause of lameness. Healing of SL injury is still problematic, and even proper rehabilitation and pharmacological therapy do not guarantee returning to the initial performance level. In our previous studies, we have shown that a combination of 5-azacytidine (AZA) and resveratrol (RES) exerts beneficial, rejuvenating effects on metabolic syndrome derived adipose-derived stem cells (ASCs). Thus, in the presented research, we investigate whether not only rejuvenated ASC but also microvesicles (MVs) secreted by them possess enhanced regenerative properties in SL injury. METHODS: In the presented study, a 6-year-old Dutch Warmblood gelding, working in jumping, was diagnosed with SL injury using ultrasonography, Doppler, real-time elastography and thermography. As a therapeutic strategy, the affected animal was treated with extracellular microvesicles derived from ASC treated with the combination of 5-azacytydine (AZA) and resveratrol (RES) (MVs)RESULTS: First, anti-apoptotic effects of MVswere tested in co-culture with metabolic syndrome derived ASC. The proliferation of cells and expression of pro-apoptotic genes were investigated. Then, MVswere injected directly into the injured SL of the Dutch Warmblood gelding. In vitro assays revealed that MVsenhance the proliferation of ASC and exert an anti-apoptotic effect. In the affected horse, the application of MVsresulted in increased lesion filling and improvement of angiogenesis and elasticity in injured tissue. CONCLUSIONS: As MVsmimic several of the biological actions exerted by ASC, they have become an alternative for stem cell-based therapies and can be effectively applied for the treatment of SL injury in horses.
