Cell adhesion and proliferation assays of different scaffolds. (a) SEM images of SMSCs adhesion on cartilage phase of scaffold loaded with or without PDGF or PDA after seeding for 1 d and 7 d. (b) SEM images of SMSC adhesion on interface layer of scaffold after seeding for 1 d and 7 d. (c) Cell proliferation of SMSCs cultured on different scaffolds after 1 d, 3 d, 5 d, and 7 d using a CCK-8 kit. Statistically significant differences are indicated with and compared with control.
