Grants We Funded

Grant applicants for the 2023 cycle requested a total of nearly $4 million dollars. The PSF Study Section Subcommittees of Basic & Translational Research and Clinical Research evaluated nearly 140 grant applications on the following topics:

The PSF awarded research grants totaling over $1 million dollars to support nearly 30 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.

Effect of SiRNA Against Noggin in Healing Calvarial Defects

Principal Investigator

Funding Mechanism
Basic Research Grant

Focus Area
Cranio/Maxillofacial/Head and Neck

The creation of a bony defect results in a hypoxic gradient wherein the oxygen tension at the center of the defect is very low. Previously, our lab has demonstrated that osteoblasts exposed to a hypoxic environment alter their expression of cytokines, bone-specific extracellular matrix molecules, and their regulators. Bone morphogenetic protein (BMP) expression has been found to decrease significantly in hypoxia. We hypothesize that the expression of noggin, a BMP inhibitor, is unaltered or increased in hypoxia, thereby altering the noggin to BMP ratio and prohibiting bone formation. Consequently, application of small interfering RNA (siRNA) to suppress noggin may restore BMP activity to normal (normoxic) levels over the long-term, restoring the balance between BMPs and BMP inhibitors and ultimately increasing the rate of new bone formation.
