| Research Abstract |
A novel food-derived collagen peptide ; Hyp-Gly was identified in the human peripheral blood. Hyp-Gly stimulated growth of primary cultured fibroblast on collagen gel. The present study also demonstrated that fibroblast migrated from mouse skin expressed peptide transporter 1 and 2 (PEPT1, 2). However, expression of PEPT1, 2 dramatically decreased after several passages. These facts suggest that absorption of the collagen peptide through PEPT1, 2 might play significant role in cell proliferation by collagen peptide.
