Publication number: 20140170117Abstract: The present disclosure is directed at a process to form bone grafting material. One may provide a porous collagen scaffold and insert the scaffold into a perfusion chamber of a perfusion flow system. This may then be followed by continuously providing a mineralization perfusion fluid flow through the scaffold at a flow rate to provide dynamic intrafibrillar mineralization of the scaffold and form a collagen/hydroxyapatite composite scaffold. One may optionally provide the scaffold with bone tissue forming cells and then deliver a perfusion fluid including oxygen and one or more nutrients through the collagen/hydroxyapatite composite scaffold and to the bone tissue forming cells at a flow rate such that the bone tissue forming cells remodel the collagen/hydroxyapatite composite scaffold and form a bone tissue extracellular matrix. The bone tissue extracellular matrix may then be decellularized to form an acellular bone repair scaffold.Type: ApplicationFiled: December 19, 2012Publication date: June 19, 2014Applicant: SOUTHWEST RESEARCH INSTITUTEInventors: Jian LING, Ben ANTEBI, Xingguo CHENG, Jeffrey N.

Publication number: 20130030548Abstract: A engineered tissue implant comprising a perfusion chamber formed with a biocompatible flexible tubular member having a wall defining an internal fluid flow passage and a porous scaffold within the fluid flow passage of the tubular member, the porous scaffold arranged such that, in a presence of a perfusion fluid, the perfusion fluid will flow through the porous scaffold and be inhibited from flow between the porous scaffold and the wall of the tubular member. The engineered tissue implant may be understood as a transplantable cell construct or as an implantable bioreactor for cell growth both in vitro and/or in vivo. A method to provide tissue for reconstruction may comprise forming the engineered tissue implant containing a scaffold, introducing and seeding cells to the scaffold, introducing a perfusion fluid to the scaffold which flows through the fluid flow passage and scaffold, proliferating the cells within the scaffold and forming blood vessels within the scaffold.Type: ApplicationFiled: July 29, 2011Publication date: January 31, 2013Applicant: SOUTHWEST RESEARCH INSTITUTEInventor: Jian LING
