Supplemented collagen peptide composition improves skin aging, elasticity, and tissue regeneration in zebrafish
A supplemented collagen peptide composition (SCPC) containing microbe-fermented collagen peptide, collagen tripeptide, elastin peptide, and sodium hyaluronate was investigated to determine its effects on skin aging, skin elasticity, and tissue regeneration in zebrafish. β-Galactosidase activity was inhibited, while telomerase activity was elevated, by exposure to 0.977 μL/mL of SCPC in an H 2 O 2 -induced aging zebrafish model, indicating that SCPC can delay cell senescence. Expression of the collagen I gene col1a1a was up-regulated by exposure to 62.5 μL/mL of SCPC, indicating that SCPC can improve skin elasticity. Regrowth of the injured caudal fin was enhanced by exposure to only 0.122 μL/mL of SCPC. These improvements to skin aging, elasticity, and tissue regeneration in zebrafish suggest that this SCPC has potential as a functional food with beneficial effects on skin health and aging resistance in humans.
