Title

Investigation the effect of copper nanoparticles on the toxicity and migration of keratinocyte cells

Abstract

 Background: Re-epithelialization has an important role in skin wound healing. Delays in re-epithelialization are more likely to create the chronic wound. Impaired wound healing leads to a large burden of morbidity and mortality. Current treatments based on the use of autografts, allografts and xenografts, suffer from limitations such as, quantity of donor skin available, donor-site infection, potential risk of disease transmission and rejection of the graft. Given this problems, nanomaterial such as copper nanoparticles has attracted considerable research interest because of their high surface area to volume ratio, high stability, clinical safety, and antibacterial effects. Epithelialization involves keratinocyte migration and proliferation to the wound site. Therefore, this study was conducted to investigate the effect of copper nanoparticles on keratinocyte cell migration and proliferation. Methods: This experimental study was performed in Royan Institute, Tehran in 2016. In this study we investigated the effect of copper nanoparticles on viability, migration and proliferation of keratinocyte cells. Cultured human foreskin Keratinocyte cells were exposed to various concentration (1, 10 and 100 μ mol) and sizes (40 and 80 nm) of copper nanoparticles for 24, 48 and 72 hours. The copper nanoparticles toxicity was examined by MTS assay. Cell migration has also been investigated with the Scratch assay. Results: The results showed that the 1, 10 and 100 μ mol concentrations of 40 and 80 nm copper nanoparticles were not toxic for cultured human foreskin keratinocyte cells after 24h. It was also found keratinocyte cell proliferation was increased by 1 μ mol concentration of 80 nm copper nanoparticles after 72h. The results of the Scratch assay showed that the 1 μ mol concentration of 80 nm copper nanoparticles significantly (P<0. 05) increased keratinocyte cell migration compared to deionized water as of control group after 24h. Conclusion: It seems the 1 μ mol concentration of 80 nm copper nanoparticle could stimulate keratinocyte cell migration and proliferation. However, in vivo studies conducted on animal model wound healing subjects are needed for determining reepithelialization.
