| 摘要 |
This invention is directed to a tissue-engineered stent comprising a substantially cylindrical construct ( 10 ) having a first end ( 12 ) and a second end ( 14 ); a walled surface ( 16 ) disposed between the first end and the second end; the walled surface ( 16 ) comprising a biodegradable polymer scaffold seeded with disassociated chondrocytes. In one embodiment, the seeded scaffold is cultured in vitro prior to implantation in a host for a time period sufficient for cartilaginous tissue to form. |
