Additive Manufacturing of Bioinspired Mineral-Based Composites

Biominerals are used by natural organisms for example as structural supports and optical sensors. They are produced from a limited number of elements and under ambient conditions. Nevertheless, they often possess excellent mechanical properties and sometim ...

Development of Standardized Fetal Progenitor Cell Therapy for Cartilage Regenerative Medicine: Industrial Transposition and Preliminary Safety in Xenogeneic Transplantation

Dominique Pioletti, Corinne Scaletta, Sandra Jaccoud, Philippe Abdel Sayed, Nathalie Hirt-Burri, Salim Elias Darwiche, Alexis Laurent

Diverse cell therapy approaches constitute prime developmental prospects for managing acute or degenerative cartilaginous tissue affections, synergistically complementing specific surgical solutions. Bone marrow stimulation (i.e., microfracture) remains a ...

Biological responses at the interface of Ti-doped diamond-like carbon surfaces for indoor environment application

Sami Rtimi

Diamond-like carbon (DLC) and titanium-doped DLC coatings were prepared by hybrid PECVD/direct current magnetron sputtering (DCMS). In this study, we show that the operating conditions of titanium-doped DLC coatings used for implants in surgical devices si ...

Osteogenesis imperfecta: from diagnosis and multidisciplinary treatment to future perspectives

Dominique Pioletti, Lee Ann Laurent-Applegate

Osteogenesis imperfecta is an inherited connective tissue disorder with wide phenotypic and molecular heterogen- eity. A common issue associated with the molecular ab- normality is a disturbance in bone matrix synthesis and homeostasis inducing bone fragil ...

Improving Osteoblast Response In Vitro by a Nanostructured Thin Film with Titanium Carbide and Titanium Oxides Clustered around Graphitic Carbon

Giovanni Longo

Introduction Recently, we introduced a new deposition method, based on Ion Plating Plasma Assisted technology, to coat titanium implants with a thin but hard nanostructured layer composed of titanium carbide and titanium oxides, clustered around graphitic ...

Osteoconductive surfaces generated from peptide functionalized poly(2-hydroxyethyl methacrylate-co-2-(methacryloyloxy)ethyl phosphate) brushes

Harm-Anton Klok, Dusko Paripovic

Modification of bone implant materials with biofunctional surfaces that facilitate osteoblast adhesion and promote matrix mineralization is an attractive strategy to improve osseointegration. This manuscript discusses the preparation and properties of RGD ...

The role of Myc in bone metabolism

Raphaëlle Stuer

Various studies have proven the involvement of Myc in cell growth and proliferation but also cell transformation and tumorigenesis. Since regulation of cell proliferation and differentiation is mandatory in bone metabolism, we investigated the role of Myc ...

In situ observation of fluoride-ion-induced hydroxyapatite-collagen detachment on bone fracture surfaces by atomic force microscopy

Georg Fantner

The topography of freshly fractured bovine and human bone surfaces was determined by the use of atomic force microscopy (AFM). Fracture surfaces from both kinds of samples exhibited complex landscapes formed by hydroxyapatite mineral platelets with lateral ...

Effect of different Ti-6Al-4V surface treatments on osteoblasts behaviour

Dominique Pioletti

The purpose of the present work was to examine the effect of different Ti-6Al-4V surface treatments on osteoblasts behaviour. Previous work in this laboratory has demonstrated that an ageing treatment reduces metal ion release from this alloy compared to s ...

Large-scale gene expression analysis of osteoblasts cultured on three different Ti-6Al-4V surface treatments

Dominique Pioletti

To improve implant biocompatibility, we developed a simple cost-effective thermal surface treatment allowing an increase in the oxide layer thickness of a titanium (Ti) alloy used in orthopaedic implants. The goal of this study was to test in vitro the rea ...
