Figure 8
Representative SEM images of the cells cultured on the porous PHBHHx scaffolds: (a) and (b) are the cells attached on the PHBHHx and SF-modified scaffolds for 1 day, respectively; (c) are the cells spreading in the pores of SF-modified scaffolds in 3 days of culture; (d) and (e) are the cell confluence on the surface and in the pores of SF-modified scaffolds, respectively, in 7 days of culture [19].
