Australian bee glue delivers a scar-fighting compound that shuts down raised scars before they take hold
Summary: Researchers from Australia have identified tomentosenol A, a compound from propolis (bee glue), that shows strong anti-scarring potential. In human cell culture models, the compound blocks key signaling pathways that drive excessive scar formation (hypertrophic and keloid scars) and promotes apoptosis (self-destruction) of scar-forming fibroblasts—mimicking the controlled resolution seen in normal wound healing. This early laboratory work addresses the need for better therapies targeting the root causes of raised, painful, and functionally limiting scars from surgery, injury, or burns. Pre-clinical trials are planned next. The discovery highlights the value of natural product research for regenerative wound care and scar management.
Key Highlights:
- Tomentosenol A from Australian propolis inhibits scarring signals and induces fibroblast apoptosis
- Promotes healing pathways similar to normal (non-scarring) wound resolution
- Potential applications: hypertrophic scars from surgery, trauma, and burns
- Researchers: Lisa Randall (lead PhD student), Fraser Russell, Trong Tran, Robert Harvey et al.
