Problem
Breast reconstruction using fat grafting is common but challenging because up to 70% of the fat injected into the chest wall can be lost.

Project
Researchers are studying if extracellular vesicles (EVs) from fat stem cells can help the fat grafts survive and stay in place better.

Outcome
The goal is to improve the success rate of fat grafting in breast reconstruction.

Future
If successful, this research could lead to more effective and lasting breast reconstruction options for women.

Update
This study looked at a method called fat grafting used in breast reconstruction after cancer. Fat is taken from one part of the body and put into the breast, but some of it can be lost. Researchers tested small particles from fat stem cells to see if they could help the fat stay in place better. They found these particles reduce inflammation and support cell growth, which could make fat grafting more successful. Funding for further research will be sought.
