摘要
Pieces of extracellular matrix (ECM), including ECM harvested from tissue donors, are used to preserve the unique characteristics of cultured cells. Using this method, cells cultured from the annulus fibrosis are more likely to retain the unique features of fibrocytes, and cells of the annulus fibrosis, if portions of annulus fibrosis ECM are included in the culture media for culturing annulus fibrosis cells. The technique is extendable to other types of cell and tissue cultures, including chondrocytes, nucleus pulposis cells, and so forth. Additional therapeutic substances may be added cell/matrix culture In addition, although the cultured cells are well suited to annulus fibrosis augmentation and/or transplantation, the invention is not limited to treatment of the intervertebral disc. For example, the invention could also be used to treat other tissues of the body such as the meniscus of the knee. The process may also be used to repair or replace other tissues or organs of the body such as the pancreas, liver, kidney, heart, etc.
