Wound healing peptides and methods of use thereof
Methods and compositions for the treatment of wounds in a mammalian subject are provided. Particularly, novel polypeptides and encoding nucleic acids that stimulate keratinocyte and endothelial cell motility and/or proliferation are provided.
1. A method to promote wound healing in a subject in need thereof, comprising administering to the subject a peptide comprising an amino acid sequence selected from the group consisting of SEQ ID NOs: 1-3.
2. The method of claim 1 , wherein the peptide is administered in an amount effective to enhance the rate of migration of keratinocytes or endothelial cells, or a combination of keratinocytes and endothelial cells, towards a wound edge.
3. The method of claim 1 , wherein the administration of the peptide results in an increase in the re-epithelialization of the wound.
4. The method of claim 1 , wherein the administration of the peptide results in an increase in angiogenesis in or near the wound.
5. The method of claim 1 , wherein the peptide is administered at a wound site.
6. The method of claim 1 , wherein the wound is a thermal, chronic, acute or surgical wound.
7. The method of claim 1 , further comprising administering to the subject a polypeptide comprising a growth factor, cytokine, or enzyme.
