Effect of platelet reach plasma on fibroblast primary culture: gene expression evaluation

Abstract

To correct skin imperfections, aesthetic medicine today makes use of injectable dermal fillers that allow filling skin by increasing the volume of soft tissue. Currently, there are many fillers usable for their excellent biocompatibility and low allergic reactions that ensure good results and good compliance. Among these, the most widely used filler is Human Plasma, obtained by centrifugation from patient blood and processed through cycles of centrifugation and heating, until it becomes a gel. In this work, we evaluated the effect of the Plasma on fibroblasts behavior in terms of cell viability, survival, growth and collagen production. To this aim, the expression levels of some adhesion and traction-resistance related genes (COL11A1, ELN, GDF6, IGF1, DSP, ELANE, HAS1, HYAL1, COL1A1 and COL3A1) were analyzed using real time Reverse Transcription-Polymerase Chain Reaction (real time RT-PCR). All genes, except for COL1A1, COL3A1 and COL11A1, were up-regulated after 24 h of treatment. Altogether, our results point out the good potential of Plasma. In particular, we appreciated an up-regulation in some of the most important genes involved in bio-revitalization, such as elastin and hyaluronic acid
