  • Urinary tract tissue graft compositions and methods for producing same
    Publication number: 20070218040
    Abstract: A method for providing a urinary tract tissue graft composition includes providing a segment of small intestinal submucosa and isolating and culturing at least one multipotent cell type from a tissue specimen of a subject. The at least one multipotent cell type is then seeded upon a surface of the segment of small intestinal submucosa and allowed to differentiate into a unipotent cell type, thereby forming a urinary tract tissue graft. Methods for repairing a damaged urinary tract tissue of a subject are also disclosed.

  • Urinary tract tissue graft compositions and methods for producing same
    Publication number: 20060105054
    Abstract: A method for repairing damaged or diseased urinary tract tissue includes providing a urinary tract tissue graft composition that includes a distal ileal segment of small intestinal submucosa. The distal ileal segment of small intestinal submucosa may be utilized as an unseeded tissue graft composition, or the distal ileal segment of small intestinal submucosa may be positioned in a tissue culture frame, and smooth muscle and urothelial cells isolated from a tissue specimen of a subject and cultured are then seeded upon the distal ileal segment of small intestinal submucosa, thereby forming a urinary tract tissue graft.

  • In vitro engineered, regenerated urinary tract tissue compositions and methods for producing same
    Publication number: 20050271635
    Abstract: A method for providing a urinary tract tissue graft composition includes providing a tissue culture frame and a segment of small intestinal submucosa and positioning the segment of small intestinal submucosa in the tissue culture frame such that the segment of small intestinal submucosa is suspended and held in a taut position by the tissue culture frame. Smooth muscle and urothelial cells are isolated from a tissue specimen of a subject and cultured, and then seeded upon the segment of small intestinal submucosa, thereby forming a urinary tract tissue graft. A tissue culture frame in which such a urinary tract tissue graft may be formed is also disclosed.
