TP8, A Novel Chondroinductive Peptide, Significantly Promoted Neo-Cartilage Repair without Activating Bone Formation.

The repair of large cartilage defects remains highly challenging in the fields of orthopedics and oral and maxillofacial surgery. A chondroinductive agent is promising to activate endogenous mesenchymal stem cells (MSCs) so as to facilitate cartilage regeneration. In this study, we analyze the crystallographic data of the critical binding domain of transforming growth factor β3 (TGF-β3) with its type II receptor and successfully develop a novel chondroinductive peptide - TGF-β3-derived peptide No.

Dicalcium silicate-induced mitochondrial dysfunction and autophagy-mediated macrophagic inflammation promotes osteogenic differentiation of BMSCs.

Dicalcium silicate (CaSiO, CS) has osteogenic potential but induces macrophagic inflammation. Mitochondrial function plays a vital role in macrophage polarization and macrophagic inflammation. The mitochondrial function of CS-treated macrophages is still unclear.

Dicalcium silicate microparticles modulate the differential expression of circRNAs and mRNAs in BMSCs and promote osteogenesis via circ_1983-miR-6931-Gas7 interaction.

Dicalcium silicate microparticle (CS)-based biomaterials have a potential for bone and dental tissue regenerative applications. The CS-mediated transcriptome level mechanism in mesenchymal stem cells (MSCs) during bone-defect healing has not been investigated yet. In this study, we elucidated the differential expression pattern of messenger RNAs (mRNAs) and circular RNAs (circRNAs) in CS-treated MSCs and their involvement in the osteogenesis process.
