Hematoxylin and Eosin stainings of longitudinal sections and histomorphometric analysis. (A_{1, 3, 5, 7}) hDPSCs-seeded scaffolds. (A_{2, 4, 6, 8}) hGFs-seeded scaffolds. (A_{1, 2}) Scaffold section overview. Blue dashed line indicates the front line of the growing tissue. Red dotted line indicates the outline of the scaffold. Scale bar = 1 mm. (A_{3, 4}) Magnifications showing vascularization in the area marked with a red box in the corresponding overview picture. Arrows indicate capillaries. Scale bar = 25 μm. (A_{5, 6}) Magnifications showing single capillaries. Scale bar = 10 μm. (A_{7, 8}) Schematic representation of the capillaries shown in 5 and 6. (B₁) Number of vessels per scaffold area. (B₂) Percent vessel area per scaffold area. Values are given as mean ± standard deviation. No statistically significant differences were found. EC, endothelial cells; hDPSCs, human dental pulp stem cells; hGFs, human gingival fibroblasts.
