The structure-property relationship between biomineralized calcium phosphate compounds upon a fluorescent quenching-recovery platform and their distinct crystalline structure and surficial functional groups are investigated. A fluorescence-based sensing platform is shown to be viable for the sensing of 8-hydroxy-2-deoxy-guanosine in simulated systems.

Unlabelled: BACKGROUND CERVUS ELAPHUS SIBIRICUS: (CES) has been traditionally used in Korean clinics to promote fracture healing based on its function of tonifying the kidneys and strengthening bones. However, experimental data supporting its efficacy are still insufficient. The aim of this study investigated the bone-union properties of CES in a femoral fracture animal model and its corresponding molecular mechanisms.

Transient amorphous phases are known as functional precursors in the formation of crystalline materials, both in vivo and in vitro. A common route to regulate amorphous calcium carbonate (ACC) crystallization is via direct interactions with negatively charged macromolecules. However, a less explored phenomenon that can influence such systems is the electrostatically driven formation of Ca-macromolecule dense phases.

The osteogenic differentiation of bone marrow-derived mesenchymal stem cells (BMSCs) is key for bone formation, and its imbalance leads to osteoporosis. Forkhead Box Protein G1 (FOXG1) is associated with osteogenesis, however, the effect of FOXG1 on osteogenesis of BMSCs and ovariectomy (OVX)-induced bone loss is unknown. In our study, FOXG1 expression in BMSCs increases after osteogenic induction.

As a recently discovered form of regulated cell death, ferroptosis has attracted much attention in the field cancer therapy. However, achieving considerably enhanced efficacy is often restricted by the overexpression of endogenous glutathione (GSH) in tumor microenvironment (TME). In this work, we report a ferroptosis-inducing strategy of GSH depletion and reactive oxygen species (ROS) generation based on a biodegradable copper-doped calcium phosphate (CaP) with L-buthionine sulfoximine (BSO) loading (denoted as BSO@CuCaP-LOD, BCCL).

Implanted biomaterials release inorganic ions that trigger inflammatory responses, which recruit immune cells whose biochemical signals affect bone tissue regeneration. In this study, we evaluated how mouse macrophages (RAW264, RAW) and mesenchymal stem cells (KUSA-A1, MSCs) respond to seven types of ions (silicon, calcium, magnesium, zinc, strontium, copper, and cobalt) that reportedly stimulate cells related to bone formation. The collagen synthesis, alkaline phosphatase activity, and osteocalcin production of the MSCs varied by ion dose and type after culture in the secretome of RAW cells.
