Improving cellular migration in tissue-engineered laryngeal scaffolds

Objective To modify the non-porous surface membrane of a tissue-engineered laryngeal scaffold to allow effective cell entry. Methods The mechanical properties, surface topography and chemistry of polyhedral oligomeric silsesquioxane poly(carbonate-urea) urethane were characterised. A laser technique introduced surface perforations. Micro computed tomography generated porosity data. Scaffolds were seeded with cells, investigated histologically...
