[Current status of bone/cartilage tissue engineering towards clinical applications]

Area of Science:

• Regenerative Medicine
• Biomaterials Science
• Orthopedic Surgery

Context:

• Mesenchymal stem cells (MSCs) exhibit osteo/chondrogenic differentiation for treating bone and cartilage defects.
• In vitro culture techniques induce bone and cartilage formation from MSCs, crucial for tissue regeneration.
• Cultured chondrocytes in atelocollagen gel are available as tissue-engineered products in Japan.

Purpose:

• To review the current status of bone and cartilage tissue engineering in Japan.
• To highlight clinical applications and advancements in regenerative medicine for orthopedic conditions.

Summary:

• Explores the in vivo and in vitro differentiation capabilities of mesenchymal stem cells (MSCs) for bone and cartilage regeneration.
• Discusses the use of cultured chondrocytes embedded in atelocollagen gel as a tissue-engineered product.
• Details the established criteria for hospitals and orthopedic surgeons distributing these advanced therapeutic products.

Impact:

• Provides insights into the clinical translation of bone and cartilage tissue engineering in Japan.
• Informs orthopedic surgeons and researchers about the current state of regenerative therapies for skeletal defects.
• Facilitates understanding of regulatory frameworks and product availability for tissue-engineered medical products.
