The scaffold is formed of a layer of mesh (e.g., Stainless Steel or Nitinol) that is tightly enclosed by a multi-layer biological matrix. The biological matrix can include three layers, such a first layer (smooth muscle cells) formed directly on the metal mesh, a second layer (fibroblast/myofibroblast cells) formed on the first layer, and a third layer (endothelial cells) formed on the second layer. The scaffold can be formed to operate as a variety of tissues, such as a heart valve or a vascular graft. For example, the mesh and corresponding biological matrix can be formed as leaflets, such that the scaffold is operable as a tissue heart valve.

    Abstract: Methods are provided for suppressing the immune system response in recipients of transplanted organs, tissues or cells. An extracorporeal quantity of blood from the intended transplant recipient is treated to induce monocytes contained in the blood to differentiate and form dendritic cells. The maturation of the dendritic cells is truncated at a stage where the dendritic cells can inactivate T cell clones which would otherwise generate an undesired immune system response. The immature dendritic cells can be directly administered to the transplant recipient, or the dendritic cells can be co-incubated with the bone marrow or stem cell preparation, prior to transplantation, in order to suppress or eliminate anti-recipient donor T cells contaminating the bone marrow or stem cell preparation. The methods can be used to suppress graft versus host disease in recipients of transplanted bone marrow or stem cells, or to suppress rejection of transplanted organs or tissue.

  • Publication number: 20120156231
    Abstract: The present invention provides isolated peptides having the amino acid sequence of SEQ ID NO: 34 or fragments thereof, which bind to HLA antigen and induce cytotoxic T lymphocyte (CTL). The present invention further provides peptides which include one, two, or several amino acid insertions, substitution or addition to the aforementioned peptides or fragments, but still have the cytotoxic T cell inducibility. Further provided are nucleic acids encoding any of these aforementioned peptides as well as pharmaceutical substances or compositions including any of the aforementioned peptides or nucleic acids. The peptides, nucleic acids, pharmaceutical substances or compositions of the present invention may be used for treating cancer or tumor.

  • Publication number: 20120148544
    Abstract: The present invention relates to methods and uses of cells for the prevention and treatment of a wide variety of diseases and disorders and the repair and regeneration of tissues and organs using low passage and extensively passaged in vitro cultured, self-renewing, colony forming somatic cells (CF-SC). For example, adult bone marrow-derived somatic cells (ABM-SC), or compositions produced by such cells, are useful alone or in combination with other components for treating, for example, cardiovascular, neurological, integumentary, dermatological, periodontal, and immune mediated diseases, disorders, pathologies, and injuries.

  • Patent number: 8198083
    Abstract: An organotypic slice and a method of preparing an organotypic slice from a central nervous system tissue, wherein the organotypic slice comprises a brain slice obtained from a brain wherein mature synapses have not been established and the organotypic slice is seeded with a population of stem cells; wherein the organotypic slice has enhanced viability as compared to an organotypic slice comprising a similar brain slice not seeded with a population of stem cells.

  • Patent number: 8198086
    Abstract: The present invention provides a method for arranging various cells as cell clusters in an arbitrary three-dimensional space and producing a three dimensional structure of a desired shape constituted exclusively by cells. Furthermore, the present invention provides a support provided with a substrate and a thread or needle-shaped material that penetrates the substrate and cell clusters for positioning cell clusters in arbitrary space. The support is provided with a sheet that can be removed as necessary for covering the substrate. Further, a method for using the support structure to position cell clusters in an arbitrary space and a method for the production of three-dimensional cell structures are provided.

  • Publication number: 20120135020
    Abstract: Peptide vaccines against cancer are described herein. In particular, epitope peptides derived from the TTK gene that elicit CTLs are provided. Antigen-presenting cells and isolated CTLs that target such peptides, as well as methods for inducing the antigen-presenting cell, or CTL are also provided. The present invention further provides pharmaceutical compositions containing as active ingredients peptides derived from TTK or polynucleotides encoding the peptides. Furthermore, the present invention provides methods for the treatment and/or prophylaxis (i.e., prevention) of cancers (tumors), and/or the prevention of postoperative recurrence thereof, as well as methods for inducing CTLs, methods for inducing anti-tumor immunity, using the peptides derived from TTK, polynucleotides encoding the peptides, or antigen-presenting cells presenting the peptides, or the pharmaceutical compositions of the present invention.
