Key result
Acellularized xenogenic porcine valved conduits implanted in goats showed progressive cellular ingrowth reaching 70% of leaflet height at 12 months without degeneration or calcification.
Why the study?
Does implantation of acellularized xenogenic porcine valved conduits lead to repopulation with autologous cells and preserve functional integrity in a goat model?

Provides proof-of-concept for autologous recellularization in a large-animal model; leaves open translation to human valve conduits.
Does implantation of acellularized xenogenic porcine valved conduits lead to repopulation with autologous cells and preserve functional integrity in a goat model?
Acellularized xenogenic porcine valved conduits demonstrate biocompatibility, progressive recellularization with autologous cells, and preservation of functional integrity without calcification up to 12 months in a goat model.
Kim et al. (2004) studied this question. Acellularized xenogenic porcine pulmonary valved conduits was evaluated on Repopulation by recipient cells and histopathologic changes. Acellularized xenogenic porcine valved conduits implanted in goats showed progressive cellular ingrowth reaching 70% of leaflet height at 12 months without degeneration or calcification.
