Summary: Oxygenating biomaterials have been found to have beneficial effects on tissue formation, but the impact of oxygen-generating materials on tissue formation is not well understood. This study investigates the effects of calcium peroxide-based oxygen-generating microparticles on the osteogenic fate of human mesenchymal stem cells (hMSCs) under severely oxygen-deficient conditions. The results show that hydrogels containing oxygen-generating microparticles improve osteogenic differentiation of hMSCs under both normal and oxygen-deficient conditions. The study also demonstrates that hydrogels with oxygen-generating microparticles can induce the formation of functional engineered tissues, holding potential for biomedical applications such as tissue regeneration and organ replacement therapy.

Summary: The study evaluated WLS expression in bone and soft tissue tumours using the YJ5 antibody, finding strong YJ5 immunoreactivity in almost all osteosarcomas, chondroblastomas, osteoblastomas, and osteoid osteomas. This marker may be useful in determining the osteogenic lineage in malignant bone tumours, especially in distinguishing osteosarcomas with unusual features.

Summary: Adipose-derived stromal/stem cells (ASCs) are promising cell sources for bone regenerative medicine. This study identified GSTT1 as a marker to predict osteogenic potential of ASC clones. Knockdown of GSTT1 reduced mineralized matrix formation in highly osteogenic ASCs, while overexpression of GSTT1 enhanced osteogenic differentiation in low osteogenic ASCs. Metabolomic analysis confirmed changes in bone differentiation-related metabolites in GSTT1-transfected ASCs. In vivo experiments showed that GSTT1-transfected ASCs significantly improved bone regeneration compared to control vector-transfected ASCs. GSTT1 can serve as a marker and therapeutic factor to enhance osteogenic differentiation of ASCs.

Summary: This study investigated the effects of a flavonoid called trifolirhizin (trifol) derived from Sophora flavescens on osteogenic processes during osteoblast differentiation. It was found that trifol promoted osteoblast differentiation markers and stimulated major osteogenic signaling proteins. Trifol also increased osteoblast-mediated bone-forming phenotypes. These findings suggest that trifol may be an effective phytomedicine for bone diseases such as osteoporosis.

Summary: The study investigated the physicochemical, biocompatible, and osteoinductive properties of gellan-chitosan incorporated with different percentages of calcium silicate in human bone-marrow mesenchymal stromal cells (hBMSCs). Results showed that the 40% calcium silicate incorporation exhibited the most promising osteogenic potential in hBMSCs, making it a potential biomaterial for treating critical bone defects.
