Cell-culture and polymer constructs

摘要

The invention is directed to the culture of cells, and particularly chondrocytes for purpose of tissue replacement. The cells are cultured on polymer constructs. Integren expression is used as a measure of chondrocyte viability. Chondrocytes are obtained from the knee, nose and ankle cartilage. Mechanical strain is used to propagate chondrocytes, chitosan and arabinogalactanchitosan are used as scaffolds. Progenitor, pluripotential, stem and mesenchymal cells are operative in this invention.
