Abstract O Plasma Rico em Plaquetas (PRP) é um preparado do sangue total que contém diversos fatores de crescimento responsáveis pela proliferação e diferenciação celular, angiogênese, como também pelo aumento da produção da matriz extracelular. Nesse sentido, o objetivo do presente estudo foi testar 10 protocolos diferentes de centrifugação para obtenção de PRP a partir do sangue total de equinos hígidos. Para isso foram utilizadas 10 amostras de 27mL de sangue total de cinco animais, as quais foram centrifugadas conforme cada protocolo proposto. Os resultados revelaram que os protocolos com menor força de centrifugação relativa resultaram em maior (p<0,05) concentração de plaquetas e, que não houve (p>0,05) influência do tempo de centrifugação em relação a essa variável. A influência do tempo foi observada apenas no número de leucócitos em protocolos com menor força de centrifugação relativa (FCR). Os quatro melhores protocolos, que obtiveram as maiores concentrações de plaquetas, foram submetidos à análise pelo teste de ELISA para dosar a quantidade de TGF-β que não revelou diferença (p>0,05) entre os protocolos. 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.
