Fig. 5From: Modularized bioceramic scaffold/hydrogel membrane hierarchical architecture beneficial for periodontal tissue regeneration in dogsHydrogel barrier effect against L-929 cells. Confocal microscopy images of cells seeded on the surface of hydrogels after 7Â days. Top: 3D reconstruction of volume observed from hydrogel top surface to a thickness where no cells can be observed. Bottom: lateral views of cells on the surface of hydrogel membranesBack to article page
