Bioactive peptides promote wound healing

Researchers have combined bioactive peptides to successfully stimulate wound healing. The in vitro and in vivo study, published today in PLoS ONE, demonstrates that the combination of two peptides stimulates the growth of blood vessels and promotes re-growth of tissue. Further development of these peptides could lead to a new treatment for chronic and acute wounds. The team tested a newly-created peptide, UN3, in pre-clinical models aimed to simulate impaired wound healing as is seen in patients with peripheral vascular diseases or uncontrolled diabetes. The peptide led to a 50 percent increase in blood vessel wall development, a 250 percent increase in growth of blood vessels, and a 300 percent increase in cell migration in response to the injury.
