erformance horses are most at risk of tendon injuries, degenerative tendinopathy and overuse tendinitis. Novel therapies aim
to restore tendon functionality by means of cell-based therapy, growth factor delivery and tissue engineering approaches. This
study examined the use of autologous mesenchymal stromal cells derived from peripheral blood (PB-MSCs), platelet rich plasma
(PRP) and a combination of both for ameliorating experimental lesions on deep digital flexor tendons (DDFT) of Bergamasca
sheep. In particular, testing the combination of blood-derived MSCs and PRP in an experimental animal model represents one
of the few studies exploring a putative synergistic action of these treatments. Effectiveness of treatments was evaluated at 30
and 120 days comparing clinical, ultrasonographic and histological features together with immunohistochemical expression
of collagen types 1 and 3, and cartilage oligomeric matrix protein (COMP). Significant differences were found between treated
groups and their corresponding controls (placebo) regarding tendon morphology and extracellular matrix (ECM) composition.
Our results indicate that the combined use of PRP and MSCs did not produce an additive or synergistic regenerative response
and highlighted the predominant effect of MSCs on tendon healing.
