Regenerative Therapy for Cartilage Damage

The subject technology discloses a tissue engineering method for treating cartilage damage. Stem cells from bone marrow are attached to a novel scaffold, hyaluronic acid-coated fibrin microbeads, and transferred to a live host to form cartilage. The regenerated cartilage is stable and not hypertrophic, which has been problematic in the current regenerative methods.

Potential Commercial Applications: Competitive Advantages:
  • A novel scaffold, hyaluronic acid-coated fibrin microbeads.
  • Cartilage repair.
  • Coating with hyaluronic acid makes the fibrin microbeads more stable for mature cartilage formation.
  • The new hyaline cartilage is stable and hypertrophy-resistant.
