Abstract

Background: Copper nanoparticles (Cu NPs) induced angiogenesis, has been adapted to respond the most important challenging in wound healing. But due to the toxicity of nanoparticles, the nontoxic concentrations is important. The aim of this study was to determine the concentration and size of copper nanoparticles for investigating the effect of its cytotoxicity on the endothelial cell.

Materials and Methods: In this study, we exposed Cu NPs (40nm) with concentrations of 1, 10, 100 μM and 1 ,10 mM to endothelial cells and evaluate its viability effect after 24, 48 and 72 hours, according to the MTS) Methy Thiazol Tetrazolium (assay. Its optical density was determined using an ELISA reader and then was recorded.

Results: The findings demonstrated that Cu NPs was significantly (p<0.05) cytotoxic in concentration higher than 100 μM and cell viability was significantly increased following 48 and 72 hours in all concentrations, so that, the most difference was seen in 100 µM concentration. The IC50 values of Cu NPs at incubation time 24, 48 and 72 hours were 31.44, 36.67 and 29.38 μM.

Conclusion: The results showed that different concentration of Cu NPs in the 48 and 72 hours didn’t cause any cytotoxicity effect, but it stimulated endothelial cell proliferation. Therefore, Cu NPs with dose and time dependent effect has been increased endothelial cell proliferation.
