Abstract: The invention disclosed herein is directed to a porous wound healing foam composition that is made from an extracellular matrix of a mammal, method of making, and method of using.

Abstract: The present invention pertains to the development of biologically derived extracellular matrices (ECM) derived from decellularized pleura tissue. Such matrices are useful in many clinical and therapeutic applications, including the repair, reconstruction, sealing, or joining of tissue, tendons, bones, and/or ligaments. In addition, the present invention features methods of making a biologically derived ECM derived from decellularized pleura tissue. The invention further features laminated ECM matrices.

Abstract: Novel bioabsorbable polymeric porous tubes for tissue engineering nerve growth are disclosed. The tubes are made from a bioabsorbable polymeric foam material and have a gradient of pore sizes across the wall thickness of the tubes such that cell growth occurs into the wall of the tubes from the inner surface, while cell growth or entry is not permitted through the outer wall into the tubular wall. The wall is permeable inwardly and outwardly to fluids. A novel method of manufacturing porous nerve tubes is also disclosed.

Abstract: A biodegradable hydrogel comprises a water-soluble dextran having aldehyde groups cross-linked with a water-soluble chitosan. Various chemical agents may be encapsulated in the hydrogel or bonded thereto for controlled release. The hydrogel may be applied as a coating to reduce the likelihood of bacterial attachment and biofilm growth; used in tissue engineering applications to prevent tissue ingrowth; or used as a matrix in which cells may proliferate. The components of the hydrogel can be applied sequentially as a spray or by immersion and will gel spontaneously at environmental or physiological temperatures.

Abstract: An integrated scaffold for bone tissue engineering has a tubular outer shell and a spiral scaffold made of a porous sheet. The spiral scaffold is formed such that the porous sheet defines a series of spiral coils with gaps of controlled width between the coils to provide an open geometry for enhanced cell growth. The spiral scaffold resides within the bore of the shell and is integrated with the shell to fix the geometry of the spiral scaffold. Nanofibers may be deposited on the porous sheet to enhance cell penetration into the spiral scaffold. The spiral scaffold may have alternating layers of polymer and ceramic on the porous sheet that have been built up using a layer-by-layer method. The spiral scaffold may be seeded with cells by growing a cell sheet and placing the cell sheet on the porous sheet before it is rolled.
