  • Publication number: 20130101659
    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: 20100068188
    Abstract: An object of the present invention is to provide technology of using a preadipocyte to restore comprehensively bone, cartilage and periodontal ligament, and cause a periodontal hard tissue to regenerate. By culturing a preadipocyte using a culture medium containing (i) at least one member selected from the group consisting of glycerophosphate and salts thereof, and (ii) at least one member selected from the group consisting of ascorbic acid, derivatives thereof and salts thereof and not containing an adrenal cortical hormone in such an amount that promotes differentiation of a preadipocyte into a periodontal hard tissue cell, differentiation of the cell into a periodontal hard tissue cell is induced efficiently. Furthermore, a scaffold is combined with the preadipocyte cultured with the above-mentioned culture medium to be transplanted into a periodontal tissue that requires regeneration.
