摘要: A defect is provided in cartilage or bone, or both, to excise damaged or pathological tissue, and it is filled with an implant having capability for complete regeneration of the skeletal tissue as a chondrogenic or osteogenic phenotype. The implant comprises cells expressing a chondrocyte phenotype (80.times.10.sup.6 cells/ml) embedded in a biocompatible matrix having about 20% serum, which provides a permissive environment for maturation and transformation of the implant to a fully integrated state with the surrounding tissue. A portion of the implant may comprise a bone segment or a bone substitute.

摘要: There are provided compositions for repairing defects of cartilage and bones. These are provided in gel form either as such, or embedded in natural or artificial bones. The gel comprises certain types of cells. These may be committed embryonal chondocytes or any kind of mesenchyme originated cells which potentially can be converted to cartilage cells, generally by the influence of chondrogenic inducing factors, in combination with fibrinogen, antiprotease and thrombin. The cells ought to be of the species to which the composition is transplanted. It is advantageous to incorporate in the gel extracellular matrix (ECM) of chondrocytes or other hormones and/or growth factors such as SM (Somatomedin=IGF-I), FGF (fibroblast growth factor), CGF (cartilage growth factor), BDGF (bone derived growth factor) or a combination of any of these.
