Caption : figure s1. (a) macroscopic view of freeze-dried pedot_0.1 scaffolds. (b) ftir spectra of pedot_0.1 scaffold. (c) the % mass loss after 28 days in culture. (d) swelling ratios of the lyophilized scaffolds after 3 h of immersion in pbs. (e) evaluation of the scaffold electrical conductivity. (f) surface porosity of both scaffold compositions depicted via sem in two magnifications (500 upper panel, and 1000 lower panel; scale bars represent 50 μm and 10 μm respectively). (g) evaluation of % surface porosity calculated via sem images using imagej. (h) macroscopic view of scaffolds when hydrated and manually compressed using a spatula. after compression, the scaffolds fully recovered retaining their initial shape (scale bar represents 4 mm). (i) stress-strain curves after uniaxial compression using mechanical testing. (j) evaluation of elastic modulus of the scaffolds at 60-90 % strain, at a velocity of 15 mm/s.

Caption : figure s2. phalloidin (red) staining showing the (a) actin cytoskeleton of pre-osteoblasts on pedot_0.1 scaffolds, (b) vinculin staining (green) indicating focal adhesion points, cell nuclei were stained with dapi (blue) (scale bar represents 50 μm). (c) metabolic activity of cells on days 1, 3, and 7.
