Abstract
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.
Claims4
The method of replacing a body part or filling a void in head and neck surgery, comprising the steps of obtaining a non-diseased, cell sample from a patient's head and neck area, rapidly growing such cells in a bioreactor and within a mold in which a replica of the patient's body part or void is produced, and surgically implanting the molded body part or void as a replacement in the patient's head and neck area, such that the molded body part or void replaces the missing body part or void and regenerates therein and fuses with the adjacent tissues in the head and neck area of the respective patient.
