• nanomaterials have been used in numerous devices and products, such as silver sulfadiazine in the treatment of burns to reduce skin infections. Furthermore, silver has been used to coat a variety of different surfaces, such as catheters [4][5][6][7], or it has been incorporated into a hydrogel network for wound

In our previous studies on the biological effects of Ag-NP (PVP-coated, 80 nm) on human mesenchymal stem cells (hMSCs), we have shown that cell activation could occur at elevated but non-toxic silver concentrations [9][10]. In addition, we have shown that hMSCs are able to ingest Ag-NP

Moreover, CeO2 nanoparticles fostered wound healing in mice due to reduction of oxidative damage [24]. However, in other studies an

• 10.3762/bjnano.5.131 Abstract Many cellular processes, such as migration, proliferation, wound healing and tumor progression are based on cell adhesion. Amongst different cell adhesion molecules, the integrin receptors play a very significant role. Over the past decades the function and signalling of
