Figure 1

PPy-coated PLA scaffolds are able to enhance ASC proliferation through electrical stimulation. (a) Scanning electron microscopy image of PLA-PPy scaffold (left) without sputtered gold layer and PLA scaffold (right) with 20 nm gold coating. (PLA scaffold could not be imaged without coating due to the heavy electrostatic.) (b) Representative images of the viable (green) and dead (red) ASCs seeded in PLA and PLA-PPy scaffolds at day 14 (scale bar: 500 μm). (c) Relative DNA content of ASCs cultured for 1, 7, and 14 days in PLA and PLA-PPy scaffolds (in the form of mean ± standard deviation, , ) (adopted from [61]).
