  • Method for production of mesenchymal cell, method for production of tooth, and mesenchymal cell for formation of tooth
    Patent number: 8574904
    Abstract: The present invention provides a method for producing mesenchymal cells for production of mesenchymal cells for formation of a tooth, the method comprising: culturing totipotent stem cells in the presence of a differentiation inducer to produce a cell population after differentiation induction treatment, the cell population containing CD44-positive and CD29-positive cells or CD44-positive and CD106-positive cells; and selecting, from the cell population after the differentiation induction treatment, the CD44-positive and CD29-positive cells or CD44-positive and CD106-positive cells as the mesenchymal cells for the formation of the tooth.
    Type: Grant

  • Minoxidil aqueous composition containing bile acid
    Patent number: 8258146
    Abstract: An object of the present invention is to provide a liquid composition wherein minoxidil can be dissolved at a relatively high concentration (the saturating amount or above), stimulation of skin and stickiness is suppressed without containing an organic solvent, and excellent effects of percutaneous absorption is achieved. The present invention provides a liquid composition comprising (i) minoxidil, (ii) bile acid or a salt thereof, and (iii) an aqueous medium in an amount of 30% by weight or more of the weight of the composition.
    Type: Grant
