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
Migration of intervertebral disc cells into dense collagen scaffolds intended for functional replacementSpringer Science and Business Media LLC - Tập 23 - Trang 813-821 - 2012

Invasion of cells from surrounding tissues is a crucial step for regeneration when using a-cellular scaffolds as a replacement of the nucleus pulposus (NP). The aim of current study was to assess whether NP and surrounding annulus fibrosus (AF) cells are capable of migrating into dense collagen scaffolds. We seeded freshly harvested caprine NP and AF cells onto scaffolds consisting of 1.5 and 3.0%...... 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

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
Gelatin-based anionic hydrogel as biocompatible substrate for human keratinocyte growthSpringer Science and Business Media LLC - Tập 23 - Trang 565-571 - 2011
Filippo Renò, Manuela Rizzi, Mario Cannas
Ionic hydrogels are biocompatible candidates for skin tissue engineering. Two hydrogels synthesized by crosslinking gelatin with polylysine (positively charged HG1) or polyglutamic acid (negatively charged HG2) were tested using spontaneously immortalized human keratinocytes (HaCaT). HaCaT cells displayed higher adhesion and proliferation onto HG2, forming a continuous and stratified epithelium af...... 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
