Figure 2

(a–c) Shows a homogeneous distribution of actin fibres and filament elongation of DPSC under the influence of EVs on (a) alloplastic, (b) allogeneic and c xenogeneic scaffolds. The magnifications of the left images were 400 × and the middle images 600 × . The images on the right are 3D reconstructions. (d–o) Photographs of scanning electron microscopy from day 7 of the DPSC cell cultures. (d, e) show DPSC on alloplastic scaffold. (f, g) DPSC + EVs on alloplastic scaffold. (h, i) shows DPSC on allogeneic scaffold. (j, k) DPSC + EVs on allogeneic scaffold. (l, m) show DPSC on xenogeneic scaffold. (n, o) DPSC + EVs on xenogeneic scaffold.
