Fig. 4From: Two differentially structured collagen scaffolds for potential urinary bladder augmentation: proof of concept study in a Göttingen minipig modelOptiMaix 2D and 3D seeded with (a) SMCs and (b) UCs before implantation. SMCs are building a multilayer on top of the fibres of the structured side of OptiMaix 2D (arrows) but are migrating inside the open pores of OptiMaix 3D. UCs are lining the dense side of OptiMaix 2D (arrows). Due to the open structure of OptiMaix 3D, UCs are also infiltrating the scaffold. Scale bar = 50 µmBack to article page
