Area of Science:

• Biomaterials Science
• Regenerative Medicine
• Nanotechnology

Background:

• Friedelin (FD) is a natural compound with anti-inflammatory, antibacterial, and wound-healing properties.
• Its potential in bone tissue engineering remains largely unexplored.
• Osteoclast differentiation and osteoblast function are critical in bone remodeling and regeneration.

Purpose of the Study:

• To investigate the biological effects of friedelin (FD) on osteoclast differentiation and osteoblast function.
• To fabricate and characterize gelatin/friedelin (Gel/FD) and gelatin/nanohydroxyapatite/friedelin (Gel/HA/FD) composite scaffolds.
• To evaluate the osteogenic potential of these novel biomaterials for bone regeneration.

Main Methods:

• Investigated FD's effects on RANKL-induced osteoclast differentiation and LPS-induced osteoblast inflammation.
• Fabricated Gel/FD and Gel/HA/FD scaffolds using freeze-drying.
• Characterized scaffolds for morphology, composition, swelling, porosity, degradation, rheology, and biocompatibility.
• Assessed osteogenic potential using Saos-2 cells, mRNA expression, and calcium deposition assays.

Main Results:

• Friedelin (FD) demonstrated protective effects on osteoblast function under inflammatory conditions.
• Composite scaffolds (Gel/FD and Gel/HA/FD) exhibited suitable physical and chemical properties for biomaterial applications.
• Scaffolds supported Saos-2 cell proliferation and osteogenic differentiation, indicated by gene expression and calcium deposition.

Conclusions:

• Friedelin (FD) is a bioactive molecule with therapeutic potential for bone regeneration.
• Gel/FD and Gel/HA/FD composite scaffolds are promising functional biomaterials for bone tissue engineering.
• Further research into FD-based biomaterials could advance bone regeneration therapies.
