Platelet-rich plasma and platelet concentrates are involved in growing factors. Both have great therapeutic potential. When the alpha-granules are released by the active platelet, they act in the lesion site stimulating the chemotaxis, the fiberplasia and the angiogenesis. They improve the regeneration of the tissue. Although these rich platelet components are easy to obtain and efficiently to prove by medicine and dentistry, their use on vet medicine is recent. So, much more control studies need to be done. This article reviews morphological aspects of platelets, action of growing factors and use of components rich in platelet in wound healing tendons, ligaments and osteo-articular structures.
