| 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. |
