Acceleration of Bone Regeneration in Critical-Size Defect Using BMP-9-Loaded nHA/ColI/MWCNTs Scaffolds Seeded with Bone Marrow Mesenchymal Stem Cells
Characterization and physicochemical properties of scaffolds. (a-d) As the concentration of MWCNT increased, the pore size, porosity, water absorption, and swelling ability decreased. (e, f) Compressive strength and compressive modulus decreased with increasing MWCNT concentrations. Mean±SD; n=3; p<0.05, p<0.01, and p<0.001.
