    Abstract: Provided are a cell sheet and a three-dimensional structure thereof that include at least mesenchymal stem cells and myoblasts isolated from a cell culture support and that are to be applied to heart disease. Use of the cell sheet and the three-dimensional structure thereof including mesenchymal stem cells and myoblasts can notably improve cardiac functions compared with a conventional technology, i.e., use of cell sheets composed of myoblasts only or mesenchymal stem cells only. Furthermore, the cell sheet itself has high strength, and the transplantation procedure is also improved.

  • Publication number: 20130095128
    Abstract: Isolated peptides derived from SEQ ID NO: 42 and fragments thereof that bind to an HLA antigen and induce cytotoxic T lymphocytes (CTL) and thus are suitable for use in the context of cancer immunotherapy, more particularly cancer vaccines, are described herein. The inventive peptides encompass both the afore-mentioned amino acid sequences and modified versions thereof, in which one, two, or several amino acids are substituted, deleted, inserted or added, provided such modified versions retain the requisite HLA binding and/or CTL inducibility of the original sequences. Further provided are nucleic acids encoding any of the aforementioned peptides as well as pharmaceutical agents, substances and/or compositions that include or incorporate any of the aforementioned peptides or nucleic acids.

  • Publication number: 20130084637
    Abstract: Herein is reported a method for obtaining a B-cell comprising the following steps a) labeling B-cells, b) depositing the labeled B-cells as single cells, c) co-cultivating the single cell deposited B-cells with feeder cells, d) selecting a B-cell proliferating and secreting IgG in step c) and thereby obtaining a B-cell. The labeling can be of IgG+CD19+-B-cells, IgG+CD38+-B-cells, IgG+CD268+-B-cells, IgG?CD138+-B-cells, CD27+CD138+-B-cells or CD3?CD27+-B-cells. The method can comprise the step of incubating said B-cells at 37° C. for one hour in EL-4 B5 medium prior to the depositing step. The method can also comprise the step of centrifuging said single cell deposited B-cells prior to the co-cultivation. In the co-cultivation a feeder mix comprising interleukin-1beta, and tumor necrosis factor alpha and Staphylococcus aureus strain Cowans cells or BAFF or interleukin-2 and/or interleukin-10 and/or interleukin-6 and/or interleukin-4 can be used.
