Mesenchymal stem cells in craniofacial reconstruction: a comprehensive review

Area of Science:

• Regenerative Medicine
• Craniofacial Surgery
• Biomaterials Science

Background:

• Craniofacial reconstruction presents significant challenges due to anatomical complexity and tissue specificity.
• Traditional tissue transplantation for craniofacial defects has limitations, including poor effectiveness stemming from differing embryonic origins of craniofacial and long bones.
• Autologous mesenchymal stem cells (MSCs) offer a potential alternative due to their pluripotency, low immunogenicity, and minimally invasive nature.

Purpose of the Study:

• To review the applications of various mesenchymal stem cell types in craniofacial repair and reconstruction.
• To explore the role of tissue engineering technologies in enhancing craniofacial defect treatment.
• To highlight the growing acceptance and promotion of autologous MSC transplantation for craniofacial reconstruction.

Main Methods:

• Review of existing literature on MSC applications in craniofacial repair.
• Analysis of studies investigating craniofacial-specific MSCs versus MSCs from other body parts.
• Examination of advancements in tissue engineering relevant to craniofacial reconstruction.

Main Results:

• Both craniofacial-specific MSCs and MSCs from other sites demonstrate significant efficacy in restoring craniofacial bones, cartilage, wounds, and adipose tissue.
• Tissue engineering technologies offer novel strategies for craniofacial repair.
• Autologous MSC transplantation is increasingly recognized and adopted for craniofacial reconstruction.

Conclusions:

• Autologous MSC transplantation is a viable and promising alternative for craniofacial reconstruction, addressing limitations of traditional methods.
• The combination of MSCs and tissue engineering holds significant potential for advancing craniofacial repair outcomes.
• Continued research and technological development will further solidify the role of MSCs in craniofacial regenerative medicine.
