摘要： The invention provides a method for forming an immobilized agent gradient within a 3-dimensional porous scaffold. A 3-dimensional scaffold formed from a biocompatible material is provided. The surface of the scaffold and/ or the agent is activated so as to allow binding of the agent to the scaffold. The activated scaffold is contacted with a solution containing the agent. Contact with the solution is maintained for a sufficient period of time to allow diffusion of the solution through a portion of the scaffold, thereby forming a desired gradient of the agent through the 3-dimensional scaffold.

摘要： The present invention provides a method for producing an anterior cruciate ligament ex vivo. The method comprises seeding pluripotent stem cells in a three dimensional matrix, anchoring the seeded matrix by attachment to two anchors, and culturing the cells within the matrix under conditions appropriate for cell growth and regeneration, while subjecting the matrix to one or more mechanical forces via movement of one or both of the attached anchors. Bone marrow stromal cells are preferably used as the pluripotent cells in the method. Suitable matrix materials are materials to which cells can adhere, such as a gel made from collagen type I. Suitable anchor materials are materials to which the matrix can attach, such as Goinopra coral and also demineralized bone. Optimally, the mechanical forces to which the matrix is subjected mimic mechanical stimuli experienced by an anterior cruciate ligament in vivo. This is accomplished by delivering the appropriate combination of tension, compression, torsion, and shear, to the matrix. The bioengineered ligament which is produced by this method is characterized by a cellular orientation and/or matrix crimp pattern in the direction of the applied mechanical forces, and also by the production of collagen type I, collagen type III, and fibronectin proteins along the axis of mechanical load produced by the mechanical forces. Optimally, the ligament produced has fiber bundles which are arranged into a helical organization. The method for producing an anterior cruciate ligament can be adapted to produce a wide range of tissue types ex vivo by adapting the anchor size and attachment sites to reflect the size of the specific type of tissue to be produced, and also adapting the specific combination of forces applied, to mimic the mechanical stimuli experienced in vivo by the specific type of tissue to be produced. The methods of the present invention can be further modified to incorporate other stimuli experienced in vivo by the particular developing tissue, some examples of the stimuli being chemical stimuli, and electro-magnetic stimuli. Some examples of tissue which can be produced include other ligaments in the body (hand, wrist, elbow, knee), tendon, cartilage, bone, muscle, and blood vessels.

摘要： A system and method for making a biomaterial device includes a support structure providing a shape for a biomaterial device. At least one applicator has a supply of biomaterial solution and is positioned along the support structure. The at least one applicator forms a biomaterial fiber by applying shear force to the biomaterial solution and delivering the biomaterial fiber to the support structure. A controller causes relative movement between the support structure and the at least one applicator, and the biomaterial fiber is arranged on the support structure according to the relative movement to form the biomaterial device. The biomaterial may be silk fibroin which may be wound onto a reciprocating and rotating mandrel. Control over the properties of the biomaterial device is achieved through appropriate selection of material processing, winding strategy, and post-winding processing.
