ABSTRACT
<p><b>OBJECTIVE</b>The effect of treated dentin matrix (TDM) to the proliferation and osteogenesis differentiation of bone marrow mesenchymal stem cells (BMSCs) is evaluated in vitro.</p><p><b>METHODS</b>TDM leaching solution was prepared by dentine particles suffering from gradient demineralization. Human BMSCs were isolated and cultivated, and subsequently cultivated in the TDM leaching solution. The proliferation of BMSCs was detected by CCK-8. The osteogenesis-related proteins, including collagen type I (Col I) and runt-related transcription factor-2 (Runx2), were extracted and detected by Western blot after a 7-day culture.</p><p><b>RESULTS</b>Compared with the control group and hydroxyapatite (HA)/β-tricalcium phosphate (βTCP) group, the proliferation of BMSCs cultivated in TDM leaching solution was significantly improved. The expression of Col I and Runx2 obviously increased after the 7-day cultivation in TDM leaching solution.</p><p><b>CONCLUSION</b>TDM can promote the proliferation and osteogenesis differentiation of BMSCs, implying the feasibility of the application in bone tissue engineering.</p>
