Fig. 2From: Two differentially structured collagen scaffolds for potential urinary bladder augmentation: proof of concept study in a Göttingen minipig modelTimeline of the in vivo study. During OPI biopsies were taken for cell cultivation and unseeded scaffolds were implanted. Six weeks later, two scaffolds implanted in OPI were excised for histological evaluation and fresh unseeded as well as autologously seeded scaffolds were implanted. Termination of the experiment was at 18, 22 and 32 after OPI. Number in brackets gives the quantity of implanted scaffoldsBack to article page
