    Abstract: The purpose of the present invention is to produce a large amount of a high-quality pluripotent stem cell stock. A mass production method of a pluripotent stem cell stock that comprises thawing starting cells followed by adhesion culture to thereby stabilize the cell conditions, and then growing the cells to a cell count that enables suspension culture. Subsequently, the cells are suspension cultured while precisely controlling the culture environment to thereby grow a large number of high-quality cells. Then, a stock is prepared at a low temperature from the cells having been grown by the suspension culture.

    Abstract: A large amount of cardiomyocyte spheroids is obtained from dissociated cardiomyocytes in a simple manner, in a short time, without using a special culture medium component, and without using a complicatedly-shaped container or a minute container. The problems can be solved by a method for producing cardiomyocyte spheroids, the method including allowing dissociated cardiomyocytes to flow under suspension conditions in a non-annular container to aggregate the cells. In addition, the problems can also be solved by a method for producing cardiomyocyte spheroids, in which the dissociated cardiomyocytes have a history of stabilization culture after thawing.

    Abstract: The present invention relates to a method for producing a formyl group-containing porous base matrix, comprising the steps of introducing a spacer in a formyl group-containing porous particle; and then oxidizing the spacer with periodic acid and/or a periodate, to transform the part of the spacer into a formyl group; wherein the formyl group content in the porous particle after introduction of the spacer is not more than 3 μmol per 1 mL of the porous particle. Also, the present invention relates to a method for producing an adsorbent, comprising the step of immobilizing an amino group-containing ligand on the formyl group-containing porous base matrix. According to the present invention, a formyl-group containing porous base matrix and an adsorbent produced from the porous base matrix of which adsorption amount is high and which is has high strength and of which ligand is difficult to be leaked are provided.

    Abstract: To provide a method for producing induced pluripotent stem cells (iPS cells) that can initialize somatic cells without using feeder cells or a substrate. For production of iPS cells, the following steps are carried out: I. introducing an initialization gene into a somatic cell; and II. performing initialization and amplification culture of the cell into which the gene has been introduced, in a liquid medium comprising at least one of a protein kinase Cβ (PKCβ) inhibitor and a WNT inhibitor under a suspension culture condition.
