A new approach to control condylar growth by regulating angiogenesis

Area of Science:

• Biomedical Science
• Developmental Biology
• Regenerative Medicine

Background:

• Mandibular condyle growth is essential for facial development and occlusion.
• Endochondral ossification is the primary mechanism driving condylar growth.
• Angiogenesis plays a critical role in the transition of cartilage to bone within the condyle.

Purpose of the Study:

• To review mandibular condyle growth mechanisms.
• To examine the function of angiogenesis regulators (enhancers and inhibitors).
• To explore novel local gene delivery methods for condylar growth regulation.

Main Methods:

• This study employed a narrative review methodology.
• Literature search focused on angiogenesis, gene delivery, and condylar growth.
• Analysis of existing research on growth factors and their delivery systems.

Main Results:

• Angiogenesis is a key process in mandibular condylar growth, facilitating cartilage-to-bone transformation.
• Vascular Endothelial Growth Factor (VEGF) and Fibroblast Growth Factor (FGF) promote angiogenesis.
• Angiostatin and endostatin inhibit angiogenesis.
• Delivery methods including liposomes, stem cells, and viral vectors have been investigated.
• Recombinant Adeno-Associated Virus (AAV)-mediated gene therapy is a promising strategy.

Conclusions:

• AAV-mediated gene therapy offers a promising approach for regulating condylar growth.
• Targeting angiogenesis with VEGF or inhibitors via gene therapy can manage early-stage condylar growth.
