Example 8
Cell adhesion was also evaluated by means of in vitro scratch wound-healing assay. HDPSCs cells were analyzed by difference in staining with phalloidin (cell nucleus) and DAPI to visualize actin cytoskeleton.
Cell adhesion results showed excellent interaction and adhesion between neighboring cells in the presence of bioceramic composition. The Bioceramic composition sealer (CB5) and Bioceramic composition repair (CB6), showed a gradual increase in growth over time, an extended morphology and a high content of F-Actin (cell microfilamen), reaching confluence after 72 hours of culture.
The analysis of cell proliferation (via cell viability study), apoptosis, cell adhesion and morphology (via cell adhesion study) and migration (via cell migration study) showed very positive results, indicating that the proposed bioceramic composition induces the odonto/osteogenic mineralization and differentiation process in the presence of tooth-specific human stem cells (hDPSCs pulp). While a market resin sealer was also used in the comparative studies, however, all results were not satisfactory for this product.
