Outline of Final Research Achievements

The present study demonstrates that Pro-Hyp increases after ingestion of meat containing collagen in addition to collagen peptide. Pro-Hyp enhances wound healing of mouse skin. The fibroblasts migrated from mouse skin have somatic stem cell marker, p75NTR, at early stage but loose p75NTR after growth. Pro-Hyp is incorporated into the fibroblasts with p75NTR and enhances growth of these cells, while fibroblasts without p75NTR do not respond.

Academic Significance and Societal Importance of the Research Achievements

コラーゲンペプチドの摂取により創傷治癒が促進されることが知られている。我々はヒト血中に見いだされていたPro-Hypは線維芽細胞を増殖せせることを見出してきたが、なぜ ProHypが正常組織の線維芽細胞を増殖せせずにダメージを持つ組織の線維芽細胞を増殖させるかが不明であった。本研究により創傷部位に集積するp75NTR陽性線維芽細胞を特異的にPro-Hypが増殖促進することが明らかになった。
