Project description:To fully interrogate mechanism of the platelet-rich plasma microneedles(PRP-MNs) in promoting hair regrowth in mice skin, we sought to perform a thorough and comprehensive transcripotome profiling of PRP-MNs,platelet-rich plasma(PRP) and microneedles(MNs) treatments of mice skin, with nective control(NC).

Project description:We studied microRNA levels in different blood compartments (erythrocytes, buffy coat, platelets (gel-filtrated or washed), PRP, PPP, and the supernatant of Convulxin-stimulated platelets). The aim of this study was to identify/confirm platelet-enriched miRNAs as biomarkers of platelet activation.

Project description:Tendon is a hypocellular tissue that contains functional cable-like units of type I collagen responsible for the transmission of force from muscle to bone. In the setting of injury or disease, patients can develop chronic tendinopathies that are characterized by pain, loss of function and persistent inflammatory changes that are often difficult to treat. Platelet-rich plasma (PRP) has shown promise in the treatment of chronic tendinopathy, but little is known about the mechanisms by which PRP can improve tendon healing. PRP contains many different growth factors and cytokines, and since these proteins can both activate and inhibit various signaling pathways it has been challenging to determine precisely which signaling pathways and cellular responses are most important. Using state-of-the-art bioinformatics tools and genome wide-expression profiling, the purpose of this study was to determine the signaling pathways activated within cultured tendon fibroblasts in response to PRP treatment. Tendon fibroblasts were isolated from rat tail tendons and embedded in 3D type I collagen gels. Cells were treated with PRP or PPP for 24 hours, and total RNA was extracted for hybridization on Affymetrix arrays.

Project description:In a whole-transcriptome study, cellular responses of DCs and macrophages confronted with the fungi A. fumigatus, platelet rich plasma (PRP) or the combination of A.fumigatus and PRP were investigated. Therefore DCs and macrophages of three independent donors were harvested after 6 hours co-culture with A. fumigatus, platelet rich plasma (PRP) or the combination of A.fumigatus and PRP and analyzed with Affymetrix whole genome expression arrays. In general, transcriptomic analysis revealed a cell type dependent clustering. Only little effects were obeserved by addition of PRP. Furthermore a clustering of A.fumigatus stimulated cells whether PRP was present or not, was observed. However, significant differences in the immune response of A.fumigauts stimuled DC and macrophages were determined.

Project description:INTRODUCTION: Differences in the metabolite profiles between serum and plasma are incompletely understood. </br> OBJECTIVES: To evaluate metabolic profile differences between serum and plasma and among plasma sample subtypes. </br> METHODS: We analyzed serum, platelet rich plasma (PRP), platelet poor plasma (PPP), and platelet free plasma (PFP), collected from 8 non-fasting apparently healthy women, using untargeted standard 1D and CPMG 1H NMR and reverse phase and hydrophilic (HILIC) UPLC-MS. Differences between metabolic profiles were evaluated using validated principal component and orthogonal partial least squares discriminant analysis. </br> RESULTS: Explorative analysis showed the main source of variation among samples was due to inter-individual differences with no grouping by sample type. After correcting for inter-individual differences, lipoproteins, lipids in VLDL/LDL, lactate, glutamine, and glucose were found to discriminate serum from plasma in NMR analyses. In UPLC-MS analyses, lysophosphatidylethanolamine (lysoPE)(18:0) and lysophosphatidic acid(20:0) were higher in serum, and phosphatidylcholines (PC)(16:1/18:2, 20:3/18:0, O-20:0/22:4), lysoPC(16:0), PE(O-18:2/20:4), sphingomyelin(18:0/22:0), and linoleic acid were lower. In plasma subtype analyses, isoleucine, leucine, valine, phenylalanine, glutamate, and pyruvate were higher among PRP samples compared with PPP and PFP by NMR while lipids in VLDL/LDL, citrate, and glutamine were lower. By UPLC-MS, PE(18:0/18:2) and PC(P-16:0/20:4) were higher in PRP compared with PFP samples. </br> CONCLUSIONS: Correction for inter-individual variation was required to detect metabolite differences between serum and plasma. Our results suggest the potential importance of inter-individual effects and sample type on the results from serum and plasma metabolic phenotyping studies. </br></br> UPLC-MS protocols and data are reported in the current study MTBLS465. </br> NMR protocols and data associated to this study are reported in MTBLS470. </br><br/> Linked Studies: <a href='https://www.ebi.ac.uk/metabolights/MTBLS470' target='_blank'><span class='label label-success'>MTBLS470</span></a>

Project description:In IVF treatment, the effects of intrauterine platelet-rich plasma (PRP) infusion with increasing rate of successful pregnancy have been reported; however, the mechanisms that support embryo implantation remain unclear. In the undifferentiated HESCs, PRP was found to strongly promote the gene expression associated with cell growth, tissue regeneration, proinflammatory response, and antibiotic effects. In decidualized HESCs, PRP was found to attenuate the gene expression involved in cell proliferation and inflammation by inhibiting the expression of PI3K signaling.

Project description:Microarray studies were performed to identify expression patterns by cryopreserved adipose stromal vascular fraction (SVF) preparations that were prepared by three different veterinary stem cell companies from the same source of canine adipose tissue. [Samples 1 - 3] Three equal samples of approximately 20 grams of adipose tissue were shipped on ice to 3 different companies which specialize in adipose-derived veterinary stem cell therapy. All 3 SVF preparations were cryopreserved at their respective facilities. Approximately one month later, cryopreserved samples were retrieved from all companies and transported frozen to the University of Kentucky for gene profiling and viability analysis. [Samples 4 - 11] Groups of cells (samples 5, 7, 9, 11) were treated by the stem cell company with photo-activated platelet-rich plasma (PRP) according to their proprietary procedures in order to enhance regenerative properties of the adipose stem cells. These PRP-treated cells were incubated in the investigator's lab for 6 hours at 37 degrees Celsius to allow for expression of genes that were induced by PRP treatment.

Project description:Platelet-rich plasma (PRP), which is prepared by concentrating platelets in autologous blood, shows efficacy in chronic skin wounds via multiple growth factors. However, it exhibits heterogeneity across patients, leading to unstable therapeutic efficacy. Human induced pluripotent stem cell-derived megakaryocytes and platelets (iMPs) are capable of providing a stable supply, holding promise as materials for novel therapies. Thus, we evaluated the effect of iMPs on wound healing in vitro. iMPs specifically released FGF2 and exhibited superior enhancement on HUVEC proliferation compared to PRP. RNA-seq revealed that iMPs induce polarization to stalk cells and enhance ANGPTL4 gene expression in HUVECs. These mechanisms were suggested to provide the superior effects of iMPs.
