Acceleration of Bone Regeneration in Critical-Size Defect Using BMP-9-Loaded nHA/ColI/MWCNTs Scaffolds Seeded with Bone Marrow Mesenchymal Stem Cells
Figure 1
Micrographs of the scaffolds with varying MWCNT content (0.5%, 1.0%, and 1.5% wt). SEM showed that nHACM scaffolds had a porous structure with well-oriented pores enclosed by a thin wall from the surface to the inside. As the concentration of MWCNT increased, the pore size and number decreased.
