Platelet-rich plasma (PRP) is a prepared of the whole blood which contains several growth factors responsible for cellular proliferation and differentiation, angiogenesis, and for the increase of the extracellular matrix. Thus, the aim of this study was to test 10 different centrifugation protocols to obtain PRP from the whole blood of healthy equines. Ten samples of 27mL of the whole blood of 5 healthy equines were used, which were centrifuged in accordance to the proposed protocols. The results showed that the protocols with less relative centrifugation force resulted in greater (p<0,05) platelets concentration. Also, platelets concentration was not influenced by varying the time of centrifugation. However, time did affect the number of leukocytes in some protocols. The best four protocols were analyzed by ELISA test to quantitate the amount of TGF-β, which revealed no difference (p> 0.05) between the protocols. |
