PROBLEM TO BE SOLVED: To provide a method and composition for producing various therapeutic agents using chondrocytes.SOLUTION: The chondrocytes genetically engineered chondrocytes can be used to express a therapeutic agent in a certain subject, including in a constant environment typically associated with chondrocytes and in a constant environment not typically associated with chondrocytes.
摘要:
The present invention describes a rapid method for preparing stem cell and physiologically acceptable matrix compositions for use in tissue and organ repair. Compared with previous tissue engineering materials, the stem cell-matrix compositions of the present invention do not require long-term incubation or cultivation in vitro prior to use in in vivo applications. The stem cells can be from numerous sources and may be homogeneous, heterogeneous, autologous, and/or allogeneic in the matrix material. The stem cell-matrix compositions as described provide point of service utility for the practitioner, wherein the stem cells and matrix can be combined not long before use, thereby alleviating costly and lengthy manufacturing procedures. In addition, the stem cells offer unique structural properties to the matrix composition which improves outcome and healing after use. Use of stem cells obtained from muscle affords contractility to the matrix composition.

Biostructures that comprises modified alginates entrapping one or more stem cells are discloses. The modified alginates comprise at least one alginate chain section to which is bonded by covalent bonding at least one cell attachment peptide. Pluralities of stem cells are also disclosed. Methods of preventing death of stem cells and cells differentiated there from are disclosed. Methods of preparing a plurality of stem cells are disclosed. Methods of treating an individual who has a degenerative disease, such as a neurological disorder, or injury involving nerve damage by administering stem cells to said individual are disclosed.

PROBLEM TO BE SOLVED: To provide a rapid method for preparing stem cells and physiologically acceptable matrix compositions for use in repair of tissue and organ. SOLUTION: The stem cell matrix compositions require no long-term incubation or cultivation in vitro prior to use by in vivo applications. The stem cells can stem from numerous sources and may be homogeneous, heterogeneous, autologous and/or allogeneic in the matrix material, and provide practicality at a medical service utility. At this time, the stem cells and matrix can be combined in a short time before use, thereby alleviating costly and lengthy manufacturing procedures. In addition, the stem cells offer unique structural characteristic to the matrix composition which improves outcome and healing after use. Use of stem cells obtained from muscle, for example, affords contractibility to the matrix composition. COPYRIGHT: (C)2008,JPO&INPIT
