A REVIEW ON HYDROXYAPATITE-BASED SCAFFOLDS AS A POTENTIAL BONE GRAFT SUBSTITUTE FOR BONE TISSUE ENGINEERING APPLICATIONS

The biocompatibility and similarity of hydroxyapatite (ha) to the mineral composition of the bone has made ha a potential candidate in bone tissue engineering (bte). over the past few decades, its application as bone graft in combination with stem cells has gained much importance. the use of bone marrow-derived mesenchymal stromal cells (mscs) will enhance the rate and quality of defect repair. however, application of hydroxyapatite as a material to develop a 3-dimension scaffold or carrier to support mscs in vitro is still in its infant stage. this review will discuss the source, manufacturing methods and advantages of using ha scaffolds in bone tissue engineering applications.
