Abstract

The present inventors identified many nuclear proteins contained in the extract of skin tissue by mass spectrometry, randomly selected multiple partial amino acid sequences of the nuclear proteins, chemically synthesized peptides consisting of the partial amino acid sequences, and examined their activity of mobilizing mesenchymal stem cells. As a result, it was found that these multiple peptides show the activity of mobilizing mesenchymal stem cells into peripheral blood, even though their amino acid sequences are completely different from each other. The inventors also found that fragment peptides of the nuclear proteins have therapeutic effects on diseases characterized by inflammation and abnormalities of the immune system (e.g., inflammatory bowel disease and psoriasis). Based on these findings, a new regenerative medicine technology that can overcome the problems of cell transplantation therapy is provided.
