Serpin A1 (alpha1-antitrypsin, alpha1-proteinase inhibitor), a potent neutrophil elastase inhibitor, has therapeutic potential as a wound-healing agent. We compared the in vitro wound-healing action of serpin A1-IGF, a recombinant fusion protein of serpin A1(M351E-M358L) and insulin-like growth factor I with that observed in the presence of natural serpin A1 or A1-C26, the synthetic C-terminal 26 residue peptide of serpin A1, previously shown to have mitogenic and antiviral activities. All agents reduced wound sizes in monolayers of the kidney epithelial cell line LLC-PK1 and in primary cultures of human skin fibroblasts. Wound reduction in primary human keratinocytes was only observed with the serpin A1-IGF chimera. None of the factors stimulated cell proliferation using a colorimetric assay, with the exception of the serpin A1-IGF chimera, which caused a significant increase of cell proliferation and thymidine incorporation in human skin fibroblasts. However, wound healing by the A1-IGF chimera was reduced in keratinocytes in the presence of mitomycin C, suggesting a role of cell proliferation in wound reduction. The hydrophobic A1-C26 peptide significantly increased the production of collagen I in skin fibroblasts, an appealing asset for skin care applications.
