摘要： A tubular tissue scaffold is described which comprises a tube having a wall, wherein the wall includes biopolymer fibrils that are aligned in a helical pattern around the longitudinal axis of the tube where the pitch of the helical pattern changes with the radial position in the tube wall. The scaffold is capable of directing the morphological pattern of attached and growing cells to form a helical pattern around the tube walls. Additionally, an apparatus for producing such a tubular tissue scaffold is disclosed, the apparatus comprising a biopolymer gel dispersion feed pump that is operably connected to a tube-forming device having an exit port, where the tube-forming device is capable of producing a tube from the gel dispersion while providing an angular shear force across the wall of the tube, and a liquid bath located to receive the tubular tissue scaffold from the tube-forming device. A method for producing the tubular tissue scaffolds is also disclosed. Also, artificial tissue comprising living cells attached to a tubular tissue scaffold as described herein is disclosed. Methods for using the artificial tissue are also disclosed.

摘要： A muscle implant includes an extracellular matrix, tendon and muscle cells. The extracellular matrix is made of a matrix of electrospun polymer fibers. The tendon is made of extruded collagen fibers and the muscle cells are disposed on the extracellular matrix in such a manner that the combination of components will functionally and structurally act as normal muscle tissue. Cardiac and smooth muscles may be similarly formed without tendons but including the extracellular matrix and muscle cells.
