Abstract
Vascular grafts made of polytetrafluoroethylene and polyethylene terephthalate have widely been used in cardiovascular surgery. The causes of delayed colonization of such grafts by endotheliocytes and mesenchymal stem cells have not been adequately investigated. The authors examined the effect of polyethylene terephthalate on the functional activity of human bone marrow mesenchymal stem cells and endothelial progenitor cells in vitro. Proliferation (MTT assay, real-time cellular impedance), migration (Boyden chamber, real-time cellular impedance), and nitric oxide production (spectrophotometciacally) by progenitor endothelial cells and mesenchymal stem cells were assessed with and without the presence of polyethylene terephthalate. The functional activity of the cells was shown to depend on the presence of polyethylene terephthalate in a well with cells. Thus, polyethylene terephthalate turned out to exhibit a toxic effect on progenitor endothelial and mesenchymal stem cells. Treatment of grafts with gelatine or fibronectin improved colonization of grafts with cells.

Abstract
In the last ten years, endothelial progenitor cells (EPCs) have gained interest as an attractive cell population in regenerative medicine for vascular applications. This population is defined as the precursor of endothelial mature cells (ECs) through a process of differentiation. To our knowledge, no single marker can be used to discriminate them from mature ECs. To effectively study their differentiation kinetics, gene expression must be assessed. Quantitative real-time PCR (RT-qPCR) is widely used to analyze gene expression. To minimize the impact of variances from RT-qPCR, a rigorous selection of reference genes must be performed prior to any experiments due to variations in experimental conditions. In this study, CD34+ mononuclear cells were extracted from human cord blood and differentiated into EPCs after seeding for a maximum period of 21 days. To choose the best combinations of reference genes, we compared the results of EPCs, CD34+ mononuclear cells, and mature endothelial cells to ensure that the differentiation kinetics did not affect the expression of our selected reference genes. The expression levels of seven genes, namely, YWHAZ, GAPDH, HPRT1, RPLP0, UBC, B2M, and TBP were thus compared. The algorithms geNorm, NormFinder, BestKeeper, and the Comparative ΔCt method were employed to assess the expression of each candidate gene. Overall results reveal that the expression stability of reference genes may differ depending on the statistical program used. YWHAZ, GAPDH, and UBC composed the optimal set of reference genes for the gene expression studies performed by RT-qPCR in our experimental conditions. This work can thus serve as a starting point for the selection of candidate reference genes to normalize the levels of gene expression in endothelial progenitor cell populations.

RGD and BMP-2 mimetic peptide crosstalk enhances osteogenic commitment of human bone marrow stem cells. Acta Biomater 2016; 36:132-42. [PMID: 27000551 DOI: 10.1016/j.actbio.2016.03.032] [Citation(s) in RCA: 81] [Impact Index Per Article: 10.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2015] [Revised: 02/19/2016] [Accepted: 03/17/2016] [Indexed: 12/16/2022]
Abstract
UNLABELLED Human bone marrow mesenchymal stem cells (hBMSCs) commitment and differentiation are dictated by bioactive molecules sequestered within their Extra Cellular Matrix (ECM). One common approach to mimic the physiological environment is to functionalize biomaterial surfaces with ECM-derived peptides able to recruit stem cells and trigger their linage-specific differentiation. The objective of this work was to investigate the effect of RGD and BMP-2 ligands crosstalk and density on the extent of hBMSCs osteogenic commitment, without recourse to differentiation medium. RGD peptide promotes cell adhesion via cell transmembrane integrin receptors, while BMP-2 peptide, corresponding to residues 73-92 of Bone Morphogenetic Protein-2, was shown to induce hBMSCs osteoblast differentiation. The immobilization of peptides on aminated glass was ascertained by X-ray Photoelectron Spectroscopy (XPS), the density of grafted peptides was quantified by fluorescence microscopy and the surface roughness was evaluated using Atomic Force Microscopy (AFM). The osteogenic commitment of hBMSCs cultured on RGD and/or BMP-2 surfaces was characterized by immunohistochemistry using STRO-1 as specific stem cells marker and Runx-2 as an earlier osteogenic marker. Biological results showed that the osteogenic commitment of hBMSCs was enhanced on bifunctionalized surfaces as compared to surfaces containing BMP-2, while on RGD surfaces cells mainly preserved their stemness character. These results demonstrated that RGD and BMP-2 mimetic peptides act synergistically to enhance hBMSCs osteogenesis without supplementing the media with osteogenic factors. These findings contribute to the development of biomimetic materials, allowing a deeper understanding of signaling pathways that govern the transition of stem cells towards the osteoblastic lineage. STATEMENT OF SIGNIFICANCE For a long time, scientists thought that the differentiation of Mesenchymal Stem Cells (MSCs) into bone cells was dictated by growth factors. This manuscript shed light on other ligands that play a crucial role in regulating MSCs fate. In concrete terms, it was demonstrated that the osteoinductive effect of BMP-2 peptide is 2 folds improved in the presence of adhesive RGD peptide. Compared to previous works highlighting this synergistic cooperation between RGD and BMP-2 peptides, the main strength of this work lies to the use of primitive human cells (hMSCs) and well-defined biomimetic material surfaces (controlled surface roughness and peptide densities). This work provides valuable insights to develop custom-designed in vitro cell culture models, capable of targeting the desired cell response.

Abstract
Peptide ligands have great potential as selective agents for diagnostic imaging and therapeutic targeting of human cancers. A number of high-throughput assays for screening potential candidate peptides have been developed. Although these screening assays are indispensable for the identification of peptide ligands at a large scale, it is crucial to validate peptide binding and selectivity for targeted receptors in a live-cell context. For testing high-affinity peptide-receptor interactions in the plasma membrane of living cells, we developed cell-resistant, micro-structured glass surfaces with high-density and high-contrast peptide features. Cell adhesion and recruitment of fluorescent receptors to micro-patterned peptides in the live-cell membrane were evaluated by reflection interference contrast (RIC) and total internal reflection (TIRF) microscopy, respectively. To demonstrate both the specificity and modularity of the assay, co-patterning of fluorescent receptors with three different immobilized micro-structured ligands was shown: first, interaction of green fluorescent protein (GFP)-tagged epidermal growth factor (EGF) receptor expressed in Jurkat cells with immobilized EGF was detected and quantified. Second, using Jurkat cells, we demonstrated specific interaction of yellow fluorescent protein (YFP)-tagged β3 integrin with c(RGDfK) peptide. Third, we identified indirect recruitment of GFP-tagged α5 integrin to an 11-mer peptide. In summary, our results show that the developed micro-structured surfaces are a useful tool for the validation and quantification of peptide-receptor interactions in their natural cellular environment.

Abstract
The long-term patency rates of vascular grafts and stents are limited by the lack of surface endothelialisation of the implanted materials. We have previously reported that GRGDS and WQPPRARI peptide micropatterns increase the endothelialisation of prosthetic materials in vitro. To investigate the mechanisms by which the peptide micropatterns affect endothelial cell adhesion and proliferation, a TAMRA fluorophore-tagged RGD peptide was designed. Live cell imaging revealed that the micropatterned surfaces led to directional cell spreading dependent on the location of the RGD-TAMRA spots. Focal adhesions formed within 3 h on the micropatterned surfaces near RGD-TAMRA spot edges, as expected for cell regions experiencing high tension. Similar levels of focal adhesion kinase phosphorylation were observed after 3 h on the micropatterned surfaces and on surfaces treated with RGD-TAMRA alone, suggesting that partial RGD surface coverage is sufficient to elicit integrin signaling. Lastly, endothelial cell expansion was achieved in serum-free conditions on gelatin-coated, RGD-TAMRA treated or micropatterned surfaces. These results show that these peptide micropatterns mainly impacted cell adhesion kinetics rather than cell proliferation. This insight will be useful for the optimization of micropatterning strategies to improve vascular biomaterials.
