Mesenchymal stromal cells (MSCs) are promising candidates in regenerative cell-therapies. However, optimizing their number and route of delivery remains a critical issue, which can be addressed by monitoring the MSCs' bio-distribution in vivo using super-paramagnetic iron-oxide nanoparticles (SPIONs). In this study, amino-polyvinyl alcohol coated (A-PVA)(More)
After accidental observations of unicellular algae trapped in the intermediate layer of Tricho­ plax, dead yeast cells were offered systematically as a food. Some of them could be found several hours later engulfed by the big tetraploid fibre cells closely beneath the dorsal epithelium of the animal. This thin epithelial sheet not only allows the expulsion(More)
In hip arthroplasty the implants' articulating surfaces can be made of a cobalt-chromium-molybdenum (CoCrMo) alloy. The use of these metal-on-metal (MoM) pairings can lead to the release of wear products such as metallic particles and dissociated metal species, raising concerns regarding their safety amongst orthopedic surgeons and the public. MoM-wear(More)
AIMS First, it will be investigated if amino-polyvinyl alcohol-coated superparamagnetic iron oxide nanoparticles (A-PVA-SPIONs) are suitable for MRI contrast enhancement in bone marrow. Second, the impact of A-PVA-SPION exposure in vivo on the viability and key functions of local bone marrow stromal cells (BMSCs) will be investigated. MATERIAL & METHODS(More)
