Fig. 2From: Cartilage progenitor cells combined with PHBV in cartilage tissue engineeringPreparation of scaffold and cell-scaffold constructs. a PHBV scaffolds were cut into cylinder shapes (5 mm diameter, 2 mm thickness). b SEM revealed the macro-porous structures of the PHBV scaffolds. c Good compatibility between the cells and the scaffold was observed on day 7. d SEM data demonstrated that CPCs adhered to the surface of the scaffold after 1 week of in vitro cultureBack to article page
