Area of Science:

  • Biomaterials Science
  • Tissue Engineering
  • Regenerative Medicine

Background:

  • Articular cartilage has limited self-repair capacity.
  • Existing thermoresponsive poly(N-isopropyl acrylamide) (pNIPAAm)-based Cell Sheet Engineering (CSE) has material limitations.
  • A novel, non-thermoresponsive CSE platform was developed for enhanced cartilage regeneration.

Purpose of the Study:

  • To develop and validate a novel, non-thermoresponsive CSE platform for functional cartilage regeneration.
  • To create a scaffold-free strategy with improved material properties for cartilage repair.

Main Methods:

  • Fabricated a culture platform by grafting poly gamma-glutamic acid (γ-PGA) and a disulfide-containing amino acid onto porous PET membranes.
  • Utilized specific cleavage of disulfide bonds by a mild reducing agent for intact cell sheet detachment with native extracellular matrix (ECM).

Main Results:

  • The hydrated substrate demonstrated biomimetic stiffness (~16.2 MPa), mimicking native cartilage.
  • The platform supported multi-layered rabbit chondrocyte sheets rich in Collagen II and Glycosaminoglycans, showing superior biocompatibility.
  • Transplanted cell sheets successfully regenerated integrated, hyaline-like cartilage in rabbit full-thickness defects within 12 weeks, confirmed by advanced imaging and histology.

Conclusions:

  • The novel CSE platform offers highly biomimetic stiffness and a gentle, chemically specific detachment mechanism.
  • This platform represents a promising clinical strategy for repairing articular cartilage defects.
  • The scaffold-free approach facilitates functional cartilage regeneration.
