Abstract

Skin lesions are associated with functional/cosmetic problems for those afflicted. Scarless regeneration is a challenge, not limited to the skin, and focus of active investigation. Recently, the host defense peptide innate defense regulatory peptide 1018 (IDR-1018) has shown exciting regenerative properties. Nevertheless, literature regarding IDR-1018 regenerative potential is scarce and limited to animal models. Here, we evaluated the regenerative potential of IDR-1018 using human 2D and 3D human skin equivalents. First, we investigated IDR-1018 using human cells found in skin—primary fibroblasts, primary keratinocytes, and the MeWo melanocytes cell line. IDR-1018 promoted cell proliferation and expression of marker of proliferation Ki-67, matrix metalloproteinase 1, and hyaluronan synthase 2 by fibroblasts. In keratinocytes, a drastic increase in expression was observed for Ki-67, matrix metalloproteinase 1, C-X-C motif chemokine receptor type 4, C-X-C motif chemokine receptor type 7, fibroblast growth factor 2, hyaluronan synthase 2, vascular endothelial growth factor, and elastin, reflecting an intense stimulation of these cells. In melanocytes, increased migration and proliferation were observed following IDR-1018 treatment. The capacity of IDR-1018 to promote dermal contraction was verified using a dermal model. Finally, using a 3D human skin equivalent lesion model, we revealed that the regenerative potential of IDR1018, previously tested in mice and pigs, is valid for human skin tissue. Lesions closed faster in IDR-1018-treated samples, and the gene expression signature observed in 2D was reproduced in the 3D human skin equivalents. Overall, the present data show the regenerative potential of IDR-1018 in an experimental system comprising human cells, underscoring the potential application for clinical investigation.
