Abstract
The present invention provides the use of spider silk threads for the production of tissue implants for medical use. A scaffolding matrix is provided for implantation, which matrix is comprised of spider silk thread and/or segments of spider silk threads which are cross-linked. The cross-linked spider silk thread segments essentially maintain a three-dimensional shape into which it is formed by pressing between molds. The three-dimensional shape obtainable by molding sufficiently stable to be used as an implant or for colonizing by mammalian cells while essentially maintaining the three-dimensional shape. In a further embodiment, the scaffolding matrix of cross-linked spider silk segments is at least partially covered by cells autologous or heterologous to the implant recipient. The matrix colonized with cells is obtainable by in vitro cultivation of isolated cells in suspension with the scaffolding matrix.
