Figure 2From: Regeneration of rabbit calvarial defects using cells-implanted nano-hydroxyapatite coated silk scaffolds Scanning electron microscopy images. A and B shows the cross section and longitudinal section of the silk scaffold respectively prior to the cell culture. Porous, interconnected structure can be observed, ×100 magnification. C and D show the cross section and longitudinal section of the silk scaffold respectively, following the cell culture, ×400 magnification. Arrows represent spreading of the cells with secreted extracellular matrix on the silk fibroin. Arrowheads represent nHA crystals on silk fibroin.Back to article page
