20080220521 | SHEET FOR GUIDING REGENERATION OF MESENCHYMAL TISSUE AND PRODUCTION METHOD THEREOF - To provide a sheet for guiding regeneration of mesenchymal tissue having improved formability, strength, absorbability and efficiency, the sheet is produced by steps of containing a culture medium in a surface of a porous sheet produced by freezing a bioabsorbable polymer material dissolved with an organic solvent and drying it, seeding a mesenchymal cell grown after taking from biotissue, and differentiating the mesenchymal cell to a mesenchymal tissue precursor cell, where the mesenchymal tissue precursor cell and an extracellular substrate are adhered on the surface of the porous sheet containing a culture medium, and the extracellular substrate is secreted in a process of the mesenchymal cell being differentiated to the mesenchymal tissue precursor cell. | 09-11-2008 |
