Grants We Funded

Grant applicants for the 2022 cycle requested a total of over $2.9 million dollars. The PSF Study Section subcommittees of Basic & Translational Research and Clinical Research evaluated 115 grant applications on the following topics:

The PSF awarded research grants totaling almost $550,000 to support 19 plastic surgery research proposals.

ASPS/PSF leadership is committed to continuing to provide high levels of investigator-initiated research support to ensure that plastic surgeons have the needed research resources to be pioneers and innovators in advancing the practice of medicine.

Role of MMP-9 in Wound Healing

Focus Area

Delayed or failed wound healing is a serious problem acutely, but with long term repercussions. Chronic wounds are the cause of suffering to thousands of patients and require an immense utilization of health care. In the bum unit, patients who heal slowly are the same ones who later struggle with scars, contractures, leading to impaired function and return to normal life. Active MMP-9 has been found at pathologically higher levels in chronic wounds when compared to a normal wound or normal skin. We believe that excess MMP-9 causes wounds to be unable to close. In the proposed project, we seek to prove our hypothesis that unbridled overexpression ofMMP-9 in keratinocytes slows the healing of wounds. Further, we then evaluate the ability of MMP-9 inhibitors to restore the slowed wound healing into a normal trajectory.
