Regenerative Potential of Perichondrium: A Tissue Engineering Perspective.

Area of Science:

• Regenerative Medicine
• Tissue Engineering
• Developmental Biology

Background:

• The perichondrium, a tissue surrounding most cartilage, is crucial for craniofacial development and growth in younger individuals.
• In adults, preserving perichondrium during surgery aids healing and cartilage maintenance, and its regenerative properties are utilized in reconstructive procedures.
• Recent advancements in tissue engineering highlight the perichondrium's essential role in creating functional cartilage for craniofacial reconstruction.

Purpose of the Study:

• To provide a comprehensive review of the perichondrium's significance in regenerative medicine and cartilage tissue engineering.
• To revisit foundational research and synthesize current literature on the perichondrium's functions.
• To emphasize the potential of the perichondrium as a source of stem and progenitor cells for regenerative therapies.

Main Methods:

• Literature review of seminal and recent studies on perichondrium.
• Analysis of the perichondrium's role in cartilage growth, maintenance, and regeneration.
• Exploration of the perichondrium's potential in tissue engineering for craniofacial reconstruction.

Main Results:
