In Vitro Behavior of Human Adipose Tissue-Derived Stem Cells on Poly(ε-caprolactone) Film for Bone Tissue Engineering Applications

Figure 8

Analysis of the proliferation of PA42-C4 grown on PCL film (red) and on PS (blue), carried out at specific experimental points (2–16 days), using the MTT assay. The relative absorbance values were measured at 570 nm. The statistical analysis was performed by linearity test and parallelism test between the two regression lines. Image A shows a representative disk of PCL with violet crystals of formazan produced from MTT conversion by PA42-C4.
