Ability of polyurethane foams to support placenta-derived cell adhesion and osteogenic differentiation: preliminary resultsSpringer Science and Business Media LLC - Tập 21 - Trang 1005-1011 - 2009

In bone tissue reconstruction, the use of engineered constructs created by mesenchymal stem cells (MSCs) that differentiate and proliferate into 3D porous scaffolds is an appealing alternative to clinical therapies. Human placenta represents a possible source of MSCs, as it is readily available without invasive procedures and because of the phenotypic plasticity of many of the cell types isolated ...... hiện toàn bộ
The influence of polymeric membrane surface free energy on cell metabolic functionsSpringer Science and Business Media LLC - Tập 12 - Trang 959-963 - 2001
L. De Bartolo, S. Morelli, A. Bader, E. Drioli
In membrane bioartificial organs using isolated cells, polymeric semipermeable membranes are used as immunoselective barriers, means for cell oxygenation and also as substrata for adhesion of anchorage-dependent cells. The selection of cytocompatible membranes that promote in vitro cell adhesion and function could be dependent on its membrane properties. In this study we investigated the physicoch...... hiện toàn bộ
Coating of intravascular balloon with paclitaxel prevents constrictive remodeling of the dilated porcine femoral artery due to inhibition of intimal and media fibrosisSpringer Science and Business Media LLC - Tập 27 - Trang 1-15 - 2016

Here we investigated how a coating of intravascular balloon with paclitaxel (drug-coated balloon; DCB, Freeway™) impacted porcine peripheral artery vascular function and remodeling. Domestic swine (n = 54) underwent percutaneous overstretch balloon dilation of femoral and iliac arteries, controlled by angiography and optical coherence tomography (OCT). Paclitaxel tissue uptake was measured at 1 h ...... hiện toàn bộ
X-ray diffraction characterization of dental gold alloy-ceramic interfacesSpringer Science and Business Media LLC - Tập 12 - Trang 215-223 - 2001
Z. Cai, I. Watanabe, J. C. Mitchell, W. A. Brantley, T. Okabe
X-ray diffraction (XRD) was employed to study dental alloy-ceramic interfaces. A Au-Pd-In alloy, which requires oxidation before porcelain firing, and a Au-Pt-Pd-In alloy, which does not require oxidation before porcelain firing, were selected in this study. Alloy specimens were centrifugally cast. Specimen surfaces were metallographically polished through 0.05 μm Al2,O3} slurries. A thin layer (<...... hiện toàn bộ
Chitosan-collagen-hydroxyapatite membranes for tissue engineeringSpringer Science and Business Media LLC - - 2022
José Becerra, Mariano Rodríguez, Dayana Leal, Karem Noris-Suárez, Gema González
AbstractTissue engineering is growing in developing new technologies focused on providing effective solutions to degenerative pathologies that affect different types of connective tissues. The search for biocompatible, bioactive, biodegradable, and multifunctional materials has grown significantly in recent years. Chitosan, calcium phosphates collagen, and their co...... hiện toàn bộ
Directional and temporal variation of the mechanical properties of robocast scaffold during resorptionSpringer Science and Business Media LLC - Tập 26 - Trang 1-8 - 2015
J. Waygood, G. E. Murch, T. Fiedler
This paper addresses the mechanical behavior of robocast PCL-Bioglass® scaffolds. These structures can be used as 3rd generation implants in tissue engineering to support the regrowth of damaged tissue, in particular bone. After successful tissue regeneration the scaffolds slowly dissolve leaving no foreign material permanently inside the body. However, to avoid mechanical separation from surround...... hiện toàn bộ
Effect of processing parameters on the microstructure and mechanical behavior of silica-calcium phosphate nanocompositeSpringer Science and Business Media LLC - Tập 21 - Trang 2087-2094 - 2010
Xueran Liu, Ahmed EI-Ghannam
Silica-calcium phosphate nanocomposite (SCPC) is a bioactive ceramic characterized by superior bone regenerative capacity and resorbability when compared to traditional bioactive ceramics. The aim of the present study is to evaluate the effect of processing parameters on the microstructure and mechanical properties of SCPC. Cylinders were prepared by pressing the ceramic powder at 200, 300 or 400 ...... hiện toàn bộ
Surface tailoring of poly(ethylene terephthalate) via ligand-tethered comb-like PEG to enhance endothelializationSpringer Science and Business Media LLC - Tập 19 - Trang 291-299 - 2007
Xiaolin Li, Jian Ji, Ming Pu, Xiaoli Wang, Jiacong Shen
The comb-like PEG (CPEG) end-tethered with l-lysine was explored to surface modification of PET to enhance endothelialization. The hydroxyl end groups of CPEG were oxygenated into aldehyde groups. The CPEG-CHO was grafted onto the aminolysized PET. The l-lysine was then end-tethered onto surface via the residual aldehyde groups. The surface modification was confirmed by ATR-FTIR, contact angle and...... hiện toàn bộ
