Effective Scarless Wound Healing Mediated by Erbium Borate Nanoparticles

The developments of nanoparticle-based treatments that benefit from novel discoveries have an essential place in the regeneration of acute and chronic wounds. Furthermore, research about the treatment methods which attempt to swiftly and scarless wound recovery has increased over time. In recent years, it has been shown that metallic-based nanoparticles, especially silver and gold derived, have an accelerating effect on chronic and contaminated wound healing. The crucial factors of inducing and completion of regeneration of wound are enhanced epithelialization rate and neovascularization in the tissue. In our study, the main purpose is the investigation of the boosting effects of erbium borate nanoparticles on the wound healing process, especially scarless ones. Newly syntesized erbium borate nanoparticles (ErB-Nps) were characterized by their concentration and particle size using nanoparticle tracking analysis (NTA). In order to examine the effect of ErB-Np on wound closure, scratch assay for dermal epithelial cells and tube formation assay for endothelial cells were performed. In addition, in order to examine the effect of the ErB-Np at a molecular level, the levels of genes related to both wound healing, inflammation, and scarless wound closure were determined with the RT-PCR experiment. Consequently, it has been shown that erbium borate nanoparticles have increased the melioration speed of scar tissue and have given clues about scarless healing potential. The investigation of the regeneration potential of erbium borate nanoparticles was done via MTS assay, quantitative PCR analysis, reactive oxygen species assay, and scratch assay. Our results show that ErB-Np is a proper agent that can be used for scarless wound healing.
