Figure 1. SEM photographs of the neat PLLA scaffold: (a) cross section, (b) vertical section and (c) outer surface, as well as the porous BF/PLLA scaffold with 15 wt% BF content: (d) cross section, (e) vertical section and (f ) outer surface.
Figure 2. Dependence of the compressive modulus and compressive strength on the fiber content in the composites. Data represent the mean ± SD, n = 5.
Figure 8. Morphology evaluation of osteoblasts on the BF/PLLA films (a), (b), (c) and (d) and the PLLA films (e), (f ), (g) and (h) by fluorescence microscopy: most cells were adherent to their substrates after 1 day: (a) and (e); cells enlarged and entered the splitting phase after 3 days: (b) and (f ); 5 days later they were fully spread (c) and (g), with cell sizes ranging from 50 to 70 μm in diameter; and 7 days later cells grew up to the formation of a complete monolayer (d) and (h) (scale bar = 50 μm).
