Research Focus

Cartilage tissue engineering with tissue-derived chondrocytes and adult stem cells. The focus is on (i) investigating the effect and mechanism of the various microenvironmental cues provided by biomimetic materials, (ii) exploring stimulation protocol(s) and device(s) that integrate material-mediated factors, for the induction and promotion of chondrogenic differentiation. One major emphasis is to manipulate stem cell differentiation to yield chondrocytes of specific zonal characteristic for the recapitulation of the zonal complexity of the cartilage tissue and regeneration of functional cartilage.

Selected Research Project

  • Control of mesenchymal stem cell chondrogenic differentiation by the manipulation of microenvironmental cues
  • Contribution of physical stimulation to stem cell chondrogenesis
  • Study of scaffold microstructural influence on chondrocytes vs MSC chondrogenic differentiation
  • Application of biophysically sorted chondrocytes in articular cartilage regeneration
