Decellularized 16 mm tissue tubes grown in vitro from human dermal fibroblasts. Ongoing studies indicate a growth capacity of decellularized engineered tissue tubes made by entrapping sheep dermal fibroblasts in a sacrificial fibrin gel tube. Laboratory testing shows decellularized engineered tissue tubes with similar physiological strength and compliance can be made from human dermal fibroblasts. These tubes are thus suitable for RVOT reconstruction in pediatric patients for a potential humanitarian device exemption clinical trial. The decellularized engineered tissue tubes, which have the feature of being allografts, could provide a one-time surgery option for these patients because they appear to exhibit growth capacity. NCC-PDI helped create a GMP master cell bank, and initiated GMP conduit fabrication manuscript submitted for pre-clinical study of non-GMP device from a prior UMN PDIC grant. NCC-PDI also provided licensing suggestions.
