Figure 6.
(A) Proliferation of MC3T3-E1 cells after 4, 7, 10 and 12 days of incubation on different PCL/HAp films, (b) topographically ordered, (c) topographically disordered and (d) flat, normalized to proliferation on control cell culture polystyrene (a). The proliferation ratio is represented as a number of cells counted per surface area for a given sample (N) normalized to the number of cells per surface area for the control sample (Nc). (B) MTT viability assay for MC3T3-E1 cells on control cell culture polystyrene (a) and on different PCL/HAp films, (b) topographically ordered, (c) topographically disordered and (d) flat, after 1, 3, 7 and 12 days of incubation. Samples for which a statistically significant difference (p < 0.05) was observed when compared to the control are denoted with *.
