Hypothesis

Dopamine may have a role in the neovascularization of dermal wound tissues and subsequently in the process of wound healing.

Conclusion

Treatment with a specific D2 dopamine receptor antagonist significantly accelerates the process of full thickness normal dermal wound healing in mice by inducing angiogenesis in wound tissues.

Supporting Evidence

  • Treatment with eticlopride significantly improved the rate of wound healing in normal Swiss mice.
  • Wound closure was 53.4% in treated groups versus 25.5% in control groups on day 5.
  • Microvessel density was significantly higher in eticlopride treated groups compared to controls.

Takeaway

Dopamine usually slows down healing, but using a special medicine can help wounds heal faster by making new blood vessels.

Methodology

The study used a murine model of full thickness dermal wound and treated mice with a D2 dopamine receptor antagonist to evaluate wound healing.

Participant Demographics

Normal Swiss mice, 4-6 weeks old, weighing 22-25 g.
