Fig. 7. Proliferation of ASCs in scaffolds by electrically stimulus (ES). (a) DNA contents of encapsulated ASCs in CNTs scaffolds as a function of culture time. (b and c) SEM images showed ASCs and BMP-2 containing CNTs matrices after 7 and 14 days of culture. Cell seeding density: 5 × 106 cell per mL gel. Values reported are an average n = 5, ±standard deviation.
