Hybrid Microspheres For Cell Encapsulation

Redouan Mahou

Cell microencapsulation is an active interdisciplinary research field. It requires the input from materials sciences, organic and physical chemistry, biology and medicine. Hydrogels are particularly suitable materials to form microspheres for cell entrapme ...

Macrophage regulation of tumor angiogenesis: implications for cancer therapy

Michele De Palma, Mario Leonardo Squadrito

This article reviews the evidence for macrophages playing an important role in the regulation of tumor angiogenesis. Findings in mouse models show that macrophages promote angiogenesis in tumors both by producing excessive amounts of proangiogenic factors ...

Controlled release nanoparticle-embedded coatings reduce the tissue reaction to neuroprostheses

Philippe Renaud, Jeffrey Alan Hubbell, Jean-Charles Bensadoun, André Mercanzini, Philippe André Guy Colin

Controlled release coatings were developed for neuroprostheses with the aim of combating the tissue reaction following implantation in the brain. The coatings consist of poly(propylene sulfide) drug-eluting nanoparticles embedded in a poly(ethylene oxide) ...

Augmentation of bone defect healing using a new biocomposite scaffold: an in vivo study in sheep

Dominique Pioletti, Pierre-Etienne Bourban, Laurence Marcelle Monique Rivier

Previous studies support resorbable biocomposites made of poly L-lactic acid (PLA) and β-tricalcium phosphate (TCP) produced by supercritical gas foaming as a suitable scaffold for tissue engineering. The present study was undertaken to demonstrate the bio ...

The tissue reaction to neuroprostheses

André Mercanzini

Neuroprostheses were developed for a variety of applications using unique microfabrication methods. A technology platform that enables novel microelectrode array designs and microfluidic channels is described. Experiments demonstrating the in vivo utility ...

The effect of lactose-conjugated silk biomaterials on the development of fibrogenic fibroblasts

Boris Hinz

Surface properties of implanted biomaterials can cause fibrotic tissue reactions by stimulating differentiation of host fibroblasts into contractile myofibroblasts. Silk fibroin (SF) protein has been used as biomaterial in pure and blended form. however, i ...

Repair of critical size defects in the rat cranium using ceramic-reinforced PLA scaffolds obtained by supercritical gas foaming

Dominique Pioletti, Pierre-Etienne Bourban, Lee Ann Laurent-Applegate, Laurence Marcelle Monique Rivier

Bioresorbable scaffolds made Of poly(L-lactic acid) (PLA) obtained by supercritical gas foaming were recently described as suitable for tissue engineering, portraying biocompatibility with primary osteoblasts in vitro and interesting mechanical properties ...

Starch-induced implant periapical lesion: A case report

This paper reports an implant periapical lesion (IPL) with a previously unreported etiology. The presence of an osteolytic area around the apex and around the middle portion of a stable Straumann hollow-screw implant was found on periapical radiographs 3.5 ...

Fetal bone cells for tissue engineering

In this thesis, the potential use of fetal bone cells for tissue engineering was evaluated. At first, fetal bone cells were characterized in vitro regarding their proliferation rate, the induction of their osteoblastic phenotype, and their antigenicity. Th ...
