  • Method of removing pluripotent cells from culture
    Patent number: 11421204
    Abstract: A stem cell removing method that certainly-removes an undifferentiated stem cell is provided. For this object, a cell group including a stem cell and a somatic cell performed differentiation induction is cultivated in culture medium composition including photosensitizer. Light of a specific wavelength is irradiated with the cell group, and the stem cell is removed, selectively. The stem cell is a pluripotent stem cell or a somatic stem cell. The pluripotent stem cell includes either an ES cell (Embryonic Stem Cell) or an iPS cell (induced Pluripotent Stem Cell). Also, somatic stem cell includes any one of a germ stem cell, a productive cell, a pluripotent stem cell and a stem cell having unipotency.

  • Method Of Differentiation From Stem Cells To Hepatocytes
    Publication number: 20170009203
    Abstract: Disclosed are: a gene transduction method for use in the induction of the differentiation of stem cells such as ES cells or iPS cells into hepatocytes effectively; stem cells into each of which a gene useful for the induction of the differentiation into hepatocytes is introduced; and hepatocytes produced from stem cells each having the gene introduced therein. A specific gene can be introduced into stem cells such as ES cells or iPS cells using an adenovirus vector. The effective induction of the differentiation into hepatocytes can be achieved by introducing the gene. Specifically, the effective induction of the differentiation of stem cells such as ES cells or iPS cells into hepatocytes can be achieved by introducing at least one gene selected from HEX gene, HNF4A gene, HNF6 gene and SOX17 gene into the stem cells.
