  Background: Several approaches for the development of tracheal substitutes for the treatment of extensive tissue defects have been explored over the years. However, a completely satisfactory approach has not been achieved. Previously, we described a composite tissue engineered trachea (TET) using chondrocytes seeded onto a polyglycolic acid (PGA) fiber-mesh. This study was considered to improve the design and functionality of the TET by using a porcine decellularized aorta as the scaffold. Methods: Chondrocytes were harvested from sheep tracheal cartilage and were suspended in medium. The chondrocytes were then seeded onto PGA and incubated in vitro for 1week. A 3x4 cm piece was cut from a decellularized aorta and four 0.5x3 cm pieces were excised from one side in a comb like fashion. A silicon stent was ins.. Read More»
