Figure 2. Effect of indirect contact between pulp fibroblasts and endothelial cells. Morphological features of endothelial cells incubated after 24 hrs in control medium without contact with pulp fibroblasts (A), and after contact with conditioned media from intact pulp cells (B) and injured pulp fibroblasts (C). The capillary network of capillary-like structure formation on the Matrigel was photographed in fresh medium under a phase-contrast microscope. Scale bar = 200 µm.
