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.

Elusive Deformable Tissue Engineered Cartilage: Focus on Elastin

Principal Investigator
John van Aalst MD

Year
2011

Institution
University of North Carolina

Funding Mechanism
Basic Research Grant

Focus Area
General Reconstructive

Abstract
The need for deformable elastic cartilage to reconstruct ear deformities, including microtia, has not been met by tissue engineering strategies. The most significant hurdle to generating deformable cartilage is the inability to control elastin production. In this project, we will utilize growth factor and nanofiber scaffold strategies to improve elastin production in umbilical cord derived mesenchymal stem cells. Scaffolding will consist of nanofibers, which are submicron fibrils, on which augmented cell growth and differentiation has been demonstrated. We will compare chondrogenesis on nanofiber mats and within nanowebs, the latter of which has a greater 3-dimensionality, and ability to interact with and influence cells. In order to test deformability, we will use microindentation techniques. For all biochemical and biomechanical parameters, we plan to compare human auricular cartilage to our tissue engineered cartilage. The potential clinical impact of generating a deformable tissue engineered elastic cartilage is significant. This cartilage will be a valuable adjunct in the reconstruction of patients with microtia and other ear abnormalities. Broader applications are also possible in patients with nasal deformities.

Biography
