Abstract

The platelet-rich plasma (PRP) is an autologous product obtained from the whole blood, which are able to stimulate tissue regeneration. The PRP is composed of platelets, which are rich in growth factors (GFs) and leucocytes (called L-PRP) that have specific functions on cellular process, such as angiogenesis, mitogenesis, chemotaxis, proliferation and differentiation. GFs are one of the three components required for cell proliferation, along with the progenitor cells that are responsible for the genic capacity, and scaffolds, which are the matrix that conducts the proliferation. Activated L-PRP are able to form fibrin networks, which are natural scaffolds. Hyaluronic acid (HA) is a glycosaminoglycan found in the extracellular matrix (ECM) and has been used combined with activated L-PRP as scaffold for cell growth, promoting a synergistic effect on bone regeneration, with successful results in clinical studies. However, there is a lack of fundamental and preclinical studies involving the interactions between cells, scaffolds and the GFs released from L-PRP. Microfluidics is a technology that has been recently used for 3D cell culture-based assays because of its many advantages over conventional culture: the creation of an in vitro microenvironment that mimics the in vivo model; the ability to precisely manipulate a tiny fluid for medium perfusion; the quantification of cell behavior in response to gradients, and the low consumption of research resources due to small volumes required. The main goal of this project is the use of growth factors released from PRP for microfluidics mesenchymal stem cells from adipose tissue from human (h-AdMCs) culture assays, and osteogenic/chondrogenic differentiation in the presence of a HA free (low and high molecular weights) or structured in sponges. Besides, we aim to perform chemotaxis and chemokinesis assays for evaluation of cells migration in response to GFs gradient. (AU)
