Overview

This study demonstrates improved activation of latent tgf-β1 in human mesenchymal stromal cells, suggesting enhanced potential for cartilage regeneration.

Key Points

  • 3D-printed polyurethane scaffolds effectively activated latent TGF-β1, enhancing cell differentiation.
  • Active TGF-β1 levels were significantly higher in mechanically loaded groups compared to controls.
  • Mechanical testing showed that higher infill densities of scaffolds resulted in increased stiffness.
  • The 16.88% infill density scaffold maintained hMSC metabolic activity, confirming low cytotoxicity.
