Cell-biomaterial interface between autologous bone marrow-derived mesenchymal stem cells and biphasic calcium phosphate scaffold

The cell-biomaterial interface between autologous bone marrow-derived mesenchymal stem cells (BMSCs) and a biphasic calcium phosphate (BCP) scaffold is a critical microenvironment in bone tissue engineering and regenerative medicine. BCP scaffolds, typically composed of a mixture of stable hydroxyapatite (HA) and more soluble beta-tricalcium phosphate (beta-TCP), provide a bioactive and osteoconductive surface that mimics the mineral phase of natural bone (PMID: 28933315). This interface facilitates BMSC attachment through integrin-mediated signaling and supports subsequent proliferation and osteogenic differentiation (PMID: 30251043). The biological response at this boundary is governed by the scaffold's surface topography, porosity, and the release of calcium and phosphate ions, which modulate intracellular signaling pathways such as BMP/Smad, Wnt/beta-catenin, and MAPK/ERK to promote bone formation (PMID: 25630841). While essential for the repair of large bone defects and non-union fractures, this interface is a multi-component system involving cellular behavior and material science rather than a discrete, druggable molecular target. Consequently, it does not fit the standard definition of a therapeutic target used in traditional pharmacology.
