Grants Funded
Grant applicants for the 2024 cycle requested a total of nearly $3 million dollars. The PSF Study Section Subcommittees of Basic & Translational Research and Clinical Research evaluated more than 100 grant applications on the following topics:
The PSF awarded research grants totaling over $650,000 dollars to support more than 20 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.

Age And ROS Alter Cell Signaling And Re-Epithelization Of Skin

Tissue Engineering, Wounds / Scar
The care of chronic wounds in the elderly in the U.S. costs approximately $25 billion annually. Wound healing is impaired in the elderly, and it is worsened by illnesses and conditions that reduce blood flow and decrease oxygen levels in wounds. These factors contribute to the generation of reactive oxygen species (ROS) in wounds, which further increases the chance that they will become chronic. The body's antioxidant defense system protects against ROS generation and damage, and the antioxidant superoxide dismutase is a key feature of this system. A significant gap in knowledge is the mechanism that makes the antioxidant system less efficient in the elderly. We will use a model of wound generation and healing that uses the commercially available skin matrix called Dermagraft®. Dermagraft® is used clinically to enhance wound healing, and it contains specialized cells from newborns that promote skin cell migration – a key feature of wound healing. In Aim 1 we will determine if ROS levels are higher in skin cells (fibroblasts and keratinocytes) from aged versus young donors, and if high ROS levels inhibit keratinocyte migration across Dermagraft®. In Aim 2 we will determine if levels of superoxide dismutase are lower in skin samples from aged versus young donors, and if low oxygen levels affect the ability of skin cells from the edge of a wound to migrate and initiate healing.
