Abstract

Platelet-rich plasma (PRP) is an autologous product prepared from whole blood with high capability to stimulate tissue regeneration. Hyaluronic acid (HA) is the main component of synovial fluid, which has multiple functions in viscossupplementation and cell signalization. In the last five years, the association of free HA and PRP has been produced clinical benefits to regenerative orthopedics. However, fundamental studies are still scarce for characterization of this association. Since 2009, the proponent group of this project, in an interdisciplinary association with the medical area, has been dedicated to the studies of basic science of PRP, and also of structural modifications of HA and its association of PRP. In this context, this project aims to broaden the spectrum of these research with the following studies: influence of the balance between platelets and leukocytes in PRP (L-PRP type) and optimization of the conditions of their preparation by centrifugation aiming standardization; influence of HA concentration gradient in centrifugation on the preparation of L-PRP; effects of the molecular weight (106, 105 and 103Da) of the free HA on proliferation of human-adipose mesenchymal cells (h-AdMSCs) and capability for differentiation in bone and cartilage; production of biomaterials for association with L-PRP: HA sponges (solid and injectable formulations); HA sponge with attached calcitonin; topical patches of HA sponges and L-PRP to reduce inflammation and joint pain relief. All the studied biomaterials will be characterized by their physicochemical properties (swelling, stability and transdermal permeation-patches), mechanical (rheology and injection force) and biological (release of growth factors and cytokines, and cell capabilities to proliferation and differentiation). This project will support 2 post-doctoral research works, 2 PhD thesis and 1 master dissertation, which will contribute to the formation of human resources and development of regenerative orthopedics.
