Comprehensive In Vitro Testing of Calcium Phosphate-Based Bioceramics with Orthopedic and Dentistry Applications.

Area of Science:

• Biomaterials Science
• Nanotechnology
• Bioceramics

Background:

• Calcium phosphates (CaPs) are a diverse class of biomaterials with significant therapeutic potential.
• Standard cytocompatibility testing (ISO 10993) is insufficient for fully understanding complex biomaterial behavior.
• In-depth characterization is needed to assess the performance of CaPs in bulk and low-dimensional forms.

Purpose of the Study:

• To review and assess current molecular techniques for characterizing CaPs biomaterials.
• To evaluate the angiogenic potential, osteogenic capability, and modulation of oxidative stress and inflammation by CaPs.
• To decipher the mechanisms of action, including signaling pathways and microRNA modulation, of CaPs.

Main Methods:

• Review of current molecular and in vitro testing technologies.
• Assessment of techniques for characterizing angiogenic and osteogenic potential.
• Analysis of methods for evaluating oxidative stress and inflammation modulation.

Main Results:

• Identified key molecular techniques for comprehensive biomaterial characterization.
• Highlighted the importance of understanding signaling pathways and microRNA involvement.
• Demonstrated the potential for advanced techniques to reveal CaP mechanisms of action.

Conclusions:

• Rigorous in vitro testing using advanced molecular techniques is essential for CaP biomaterials.
• Understanding molecular mechanisms will facilitate the selection of effective therapeutic bioceramics.
• This approach enables the development of application-ready, innovative CaP-based solutions.
