Cell–matrix adhesion interface on dentine graft

The cell–matrix adhesion interface on a dentine graft refers to the complex structural and biochemical boundary where host cells, such as osteoblasts and mesenchymal stem cells, attach to the surface of a dentine-derived scaffold (PubMed: 31254321). Dentine grafts, particularly autogenous ones, are increasingly used in regenerative dentistry because their composition—rich in Type I collagen and hydroxyapatite—closely mimics human bone (NCBI: PMC6627831). The adhesion interface is primarily mediated by the binding of cellular integrin receptors to extracellular matrix proteins like osteopontin and bone sialoprotein embedded within the dentine matrix (Journal of Periodontal Research). This binding event initiates intracellular signaling through focal adhesion kinase (FAK) and other pathways, which are vital for cell survival, migration, and subsequent osteogenic differentiation (PubMed: 28452145). While not a single molecular target for drug therapy, this interface is a critical focus for biomaterial engineering to enhance the integration of grafts in alveolar ridge preservation and bone defect repair. Optimizing the topography and protein availability at this interface can significantly improve clinical outcomes in dental and orthopedic surgeries.

Not applicable as this is a structural interface rather than a molecular drug target; however, it facilitates osteoconduction and osteoinduction through integrin-mediated cell attachment.
