  • Submucosa gel as a growth substrate for cells
    Patent number: 5866414
    Abstract: A cell culture growth substrate comprising submucosal tissue of a warm-blooded vertebrate and a method for culturing eukaryotic cells are described. Submucosal tissue used in accordance with the present invention supports the proliferation and differentiation of eukaryotic cells when said cells are contacted with submucosal tissue under conditions conducive to cell proliferation.
    Type: Grant
    Filed: September 19, 1995
    Date of Patent: February 2, 1999
    Inventors: Stephen F. Badylak, Sherry Voytik, George Boder
  • Method for enhancing functional properties of submucosal tissue graft constructs
    Patent number: 5753267
    Abstract: A tissue graft construct comprising submucosal tissue of a warm-blooded vertebrate and a proliferating population of cells is described. The submucosal graft constructs used in accordance with the present invention induce host tissue proliferation, remodeling and regeneration of appropriate tissue structures upon implantation in a host.

  • Method of repairing bone tissue
    Patent number: 5641518
    Abstract: A method for repairing damaged or diseased bone is described. The method comprises the step of implanting into the damaged or diseased region a bone graft composition in powder form, the composition comprising the tunica submucosa delaminated from the tunica muscularis and at least the luminal portion of the tunica mucosa of a segment of vertebrate intestine.

  • Fluidized intestinal submucosa and its use as an injectable tissue graft
    Patent number: 5516533
    Abstract: A fluidized, injectable tissue graft composition is described. The composition comprises comminuted intestinal submucosa or protease-digested intestinal submucosa. Methods for the preparation and use of injectable tissue graft compositions are described. In preferred embodiments the tissue graft material is prepared from the intestinal submucosa comprising the tunica submucosa, the muscularis mucosa and the stratum compactum of a segment of intestinal tissue of a warm-blooded vertebrate. Effective amounts of the fluidized graft compositions can be injected to promote repair tissue defects by inducing formation of endogenous tissues.
