Fig. 3From: Mesenchymal stem cell-loaded porous tantalum integrated with biomimetic 3D collagen-based scaffold to repair large osteochondral defects in goatsCharacteristics of the CM-pTa scaffold and cell adhesion in vitro. a The appearance of BMSCs/pTa-chondrocytes/CM biphasic scaffold, b the interface between pTa and CM, c the component of CM, and d pTa analyzed by energy spectrum. e Morphology of chondrocytes cultured on CM, f CM control, g BMSCs cultured on pTa, and h pTa control was observed by SEM. For panels e, f, g, and h, big image was magnified × 300, bar = 50μm; small image was magnified × 1000, bar = 10μmBack to article page
