Focus Area
Tissue Engineering

An ideal soft tissue substitute for reconstructive and aesthetic surgery has still not been identified. Alloplastic implants are prone to complications such as extrusion, infection, and capsular contracture. Autologous fat transplantation will undergo resorption. Tissue flap reconstruction is effective in many cases, but still has inherent donor site morbidity. A durable tissue engineered implant using a patient's own cells may represent a better clinical option. While preadipocytes can be induced to differentiate in-vitro with the use of an adipogenic medium, these cells would not be exposed to the same concentration of growth factors when implanted in-vivo. Therefore, many cells may survive as undifferentiated precursors instead of forming new fat tissue. Our group has developed a novel polymer scaffold that incorporates the adipogenic growth factors from our differentiation medium and releases these factors to the adherent cells during degradation. This would allow implantation of preadipocytes on a scaffold that not only provides structural support, but also stimulates the surrounding cells to an adipocyte phenotype. The polymer is designed so that the release of growth factors during degradation correlates with the time period required for adipocyte differentiation. The purpose of this study is to engineer a soft tissue implant using human preadipocytes seeded on a biodegradable polymer scaffold that integrates growth factors in its chemical structure.
