  • Publication number: 20230357696
    Abstract: Disclosed herein are details of a hermetically or aseptically sealed bioreactor. The bioreactor comprises a bioreactor chamber, a membrane wall, a scaffold structure, a linear actuator, a linear transfer means, and a control system. Use of the bioreactor permits the inner scaffold structure to be moved and manipulated while still preserving a hermetic or aseptic seal inside the bioreactor chamber during operation.

  • Patent number: 11324857
    Abstract: Provided herein are methods of culturing organized skeletal muscle tissue from precursor muscle cells by cyclically stretching and relaxing said muscle cells on a support in vitro for a time sufficient to produce said organized skeletal muscle tissue, including reseeding said organized skeletal muscle tissue by contacting additional precursor muscle cells to said organized skeletal muscle tissue on said solid support, and then repeating said step of cyclically stretching and relaxing said muscle cells in said support in vitro for time sufficient to enhance the density (i.e., increased number of nuclei and/or number of multinucleated cells) of said organized skeletal muscle tissue on said support.

  • Patent number: 9114196
    Abstract: Methods are provided for producing a bioscaffold from natural tissues by oxidizing a decellularized tissue to produce a bioscaffold having pores therein. The pore size and porosity is increased to better accommodate intact cells so that live cells can better infiltrate and inhabit the bioscaffold. The bioscaffold may be freeze-dried or lyophilized, sterilized and (optionally) aseptically packaged for subsequent use. A further aspect of the present invention is a bioscaffold produced by the processes described herein. Methods of treatment using the bioscaffold as a graft or as a biomedical implant for implantation are also provided. Also provided are methods of seeding a bioscaffold with mammalian cells, wherein the seeding carried out either in vitro or in vivo, and wherein a bioscaffold produced as described herein is utilized for said seeding.
