There is an endogenous electric field in living organisms, which plays a vital role in the development and regeneration of bone tissue. Therefore, self‐powered piezoelectric material for bone repair has become hot research in recent years. However, the current piezoelectric materials for tissue regeneration still have the shortcomings of lack of biological activity and three‐dimensional structure...
The objectives of this study were to incorporate iron oxide nanoparticles (IONPs) into calcium phosphate cement (CPC) to enhance bone engineering, and to investigate the effects of IONPs as a liquid or powder on stem cells using IONP-CPC scaffold for the first time. IONP-CPCs were prepared by adding 1% IONPs as liquid or powder. Human dental pulp stem cells (hDPSCs) were seeded. Subcutaneous implantation...
Recent studies have shown that block wnt/β-catenin signaling pathway is integrant for cardiomyocytes differentiation from bone marrow mesenchymal stem cells (MSCs). By transducing the MSCs with lentivirus which contain β-catenin interference RNA, we screened out the non β-catenin expression clone. In the establishment of knockdown β-catenin in MSCs, we investigated the role of 5-azacytidine (5-aza),...
