    摘要: A method for production of large numbers of cartilage cells with phenotype retention intended for treatment of articular cartilage lesions or preparing viable cartilage tissue by propagation of chondrocytes from cartilage explants, human or animal, with the retention of phenotypes of the cartilage cells, in which cells are chondrocytes retaining morphologic attributes of the same or chondrocyte progenitor cells. The method includes culturing the cells in which cultured cells are organized into mature hyaline cartilage on the surface of biologic structures such as cancellous or cortical bone lamina. The method for culturing chondrocytes to produce three dimensional cellular structures consisting of cartilage cells and cell produced extracellular cartilage matrix.

    摘要: Provided is an acellular mammalian tooth-shaped scaffold including a compound that is chemotactic, osteogenic, dentinogenic, amelogenic, or cementogenic. Also provided is a method of replacing a tooth in the mouth of a mammal, where the tooth is absent and a tooth socket is present in the mouth at the position of the absent tooth. The method includes implanting an acellular scaffold having the shape of the missing tooth into the tooth socket. Additionally, a method of making a tooth scaffold is provided. The method includes synthesizing an acellular scaffold in the shape of a mammalian tooth and adding at least one compound that is chemotactic, osteogenic, dentinogenic, amelogenic, or cementogenic.

    摘要: Porous HCG scaffolds are provided in a perfusion bioreactor. Cells are seeded in the HCG scaffolds and cell culture media is perfused through the bioreactor to allow for cell seeding and growth. The cell culture media is removed, the HCG-cell constructs washed, and then preserved in the bioreactor with a perfusion comprising cryopreservation fluid comprising one or more of DMSO, trehalose, glycerol, ethylene glycol, or serum. The HCG-cell constructs (or the perfusion chambers containing them) are then removed from the bioreactor and placed in a cryopreservant media and maintained at about −80° C. The frozen HCG-cell constructs (or the chambers containing them) can then be stored at a suitable cryogenic temperature until needed. When needed, frozen HCG-cell constructs can be removed from cold storage and thawed using suitable means.

    摘要: An implant for articular cartilage repair includes (1) a three-dimensional body formed of cancellous bone having a demineralized section that contains bone morphogenetic proteins (BMP's) that are released by the demineralization but retained in the body, and (2) a cartilage layer formed on a surface of the demineralized section. The cartilage layer is formed by a method including the steps of (a) isolating chondrocytes from articular cartilage of a donor; (b) cultivating the isolated chondrocytes in a medium; (c) adding the cultivated chondrocytes to the demineralized section of the body, whereby the cultivated chondrocytes are stimulated by the BMP's retained in the body; and (d) incubating the cultivated chondrocytes to form a plurality of layers of chondrocytes on the demineralized section, wherein the plurality of layers of chondrocytes forms the cartilage layer.
