  • Patent number: 9695445
    Abstract: An objective of the present invention is to provide vectors for conveniently and efficiently producing ES-like cells in which foreign genes are not integrated into the chromosome. The present inventors discovered methods for producing ES-like cells from somatic cells using chromosomally non-integrating viral vectors. Since no foreign gene is integrated into the chromosome of the produced ES-like cells, they are advantageous in tests and research, and immunological rejection and ethical problems can be avoided in disease treatments.

  • Patent number: 9206391
    Abstract: This invention provides a method for preparing biological tissue in which the thickness (i.e., the number of cell layers) can be easily regulated, culture can be conducted within a shorter period of time than is possible with conventional techniques, and addition of unfavorable components is not necessary. The method of the invention comprises adding a cell-containing culture solution to a culture vessel having a non-cell-adhesive inner bottom surface, conducting cell culture while centrifugal force toward the inner bottom surface is applied to the cells in the vessel, forming tissue via intercellular adhesion, and detaching and collecting the resulting tissue from the inner bottom surface.

  • Patent number: 9193779
    Abstract: The present invention discloses protein fragment including a cell binding region of fibronectin and methods of using the same for cell culture. Additionally, surfaces modified with such protein fragment and compositions including the same are provided. Desirably, such surfaces allow various cells to adhere thereto yet avoid issues associated with animal-derived products.

  • Patent number: 9168125
    Abstract: Artificial dermis (1) obtained from plasma with platelets (2) and human fibroblasts. The plasma with platelets (2) is obtained from the fractionating of total blood (4) from the patient (8) by light centrifugation, and the human fibroblasts (3) from a skin biopsy, (5). Clotting is obtained by adding calcium. This artificial dermis (1) permits rapid growth of the keratinocytes (6) seeded on its surface to build an artificial skin (7) which can easily be transplanted. Large areas of artificial dermis (1) are obtained from small amounts of starting materials and can be enriched with cytokines and platelet growth factors, to strengthen proliferation of the cells seeded. The artificial skin (7) obtained can be used to treat major burn treatments, chronic skin ulcers, etc., or be used, by employing genetically altered cells, as a vehicle for gene therapy.

  • Patent number: 9157061
    Abstract: We used ACCUTASE®, a commercially available cell detachment solution, for single cell propagation of pluripotent hESCs. Unlike trypsin dissociation, ACCUTASE® treatment does not significantly affect the plating efficiency of hESC dissociation into single cells. Cultures dissociated with ACCUTASE® to single cells at each passage maintain a higher proportion of pluripotent cells as compared to collagenase-passaged hESCs. ACCUTASE®-treated hESCs can be grown to a high density as monolayers, and yet retain their pluripotency.
