Evaluation of keeping quality of canine platelet rich plasma under different storage conditions

Platelet rich plasma (PRP) therapy is an integral part of regenerative medicine as the platelets possess a good healing capacity owing to the presence of a wide variety of growth factors in the platelet granules found in the cytoplasm of the platelet. Autologous PRP was prepared from the blood of the patient itself, without any preservatives. Storage of PRP was one of the main hurdles of the treatment modality. During storage, the platelet counts may get reduced, undergo activation or get contaminated with bacteria as no preservatives are used in the preparation of autologous PRP. Cytological changes and microbial quality of the PRP during storage at 4oC and -20oC for seven days were analysed in this study. Reduction in platelet count and the chance of microbial contamination were less when autologous PRP was stored at -20°C compared to 4°C
