Insight into the Internal Structure of Biogenic, Synthetic and Geological Apatite by Electron Microscopy and X‐Ray Scattering

Advanced Functional Materials, EarlyView.
Apatite occurs in many forms in nature, e.g. in teeth and geological minerals. Internally, biological apatite contains nanocrystals that are also found in synthetically prepared calcium phosphate nanoparticles which are used in biomedicine, e.g. for gene and drug delivery and for bone regeneration. Abstract Calcium phosphate is the inorganic component (

Si Inhibited Osteoclastogenesis: The Role of Fe and the Fenton Reaction

Advanced Healthcare Materials, EarlyView.
Silicate (Si) inhibition of osteoclastogenesis, is mediated by Fe. Si chemical interactions with Fe inhibit the Fenton reaction and intercellular ROS availability. This reduction in ROS availability inhibits osteoclastogenesis. The addition of Fe, in Si‐inhibited osteoclast cultures, restores the Fenton reaction, and osteoclastogenesis.

Bone‐Derived dECM Hydrogels Support Tunable Microenvironments for In Vitro Osteogenic Differentiation

Advanced Healthcare Materials, EarlyView.
A tunable methacrylated decellularized bone matrix hydrogel (dECM‐MA) is developed to support 3D culture of human osteoblasts. The hydrogel preserves bone‐specific ECM cues and allows precise control over mechanical properties. This system provides a customizable platform for studying osteogenic differentiation and modeling bone tissue environments for

DSP and DPP are dispensable for initiation of dentin and enamel mineralization but critical for circumpulpal dentin mineralization

Scientific Reports
Dentin sialophosprotein (DSPP) is cleaved into the N-terminal dentin sialoprotein (DSP) proteoglycan and the C-terminal dentin phosphoprotein (DPP; the most acidic proteins in humans).

An Innovative “Tooth‐On‐Chip” Microfluidic Device Emulating the Structure and Physiology of the Dental Pulp Tissue

Advanced Healthcare Materials, EarlyView.
This work presents a “tooth‐on‐chip” device that mimics dental pulp tissue. By co‐culturing key cell types, it recreates vascular networks, stem cell niches, the odontoblast/dentine interface, and trigeminal innervation. This innovative platform provides a unique model of dental pulp structure and physiology, with significant potential for accelerating

Successful amplification of mitochondrial DNA from dentin of the bottlenose dolphin Tursiops truncatus

Brazilian Archives of Biology and Technology, 2007
Twenty-four teeth of Tursiops truncatus from the collection of the Marine Mammals Laboratory (FURG-RS) were analysed for their potential as DNA source for population genetic and taxonomic studies. All teeth were submitted to decontamination, grinding and

Biomimetic Mineralization of Keratin Scaffolds for Enamel Regeneration

Advanced Healthcare Materials, EarlyView.
Keratin‐based films guide biomimetic enamel remineralization by promoting organized hydroxyapatite growth under physiological conditions. Advanced biophysical characterization confirms keratin's structural adaptability and mineral ions‐binding affinity, supporting mineral nucleation and hierarchical crystal assembly. This study establishes keratin as a
