  • Method for cultivation of hair follicular dermal sheath cells
    Patent number: 8206980
    Abstract: A method for culture of hair follicular dermal sheath cells or precursor cells thereof which are potent cellular materials for such as hair regeneration by cell transplantation is provided. That is, by performing culture in an animal cell culture medium supplemented with platelet-derived growth factor AA (PDGF-AA) and fibroblast growth factor 2 (FGF2), hair follicular dermal sheath cells are proliferated while sustaining their function, or hair follicular dermal sheath precursor cells are differentiated into dermal sheath cells and proliferated.
    Type: Grant
    Filed: October 2, 2006
    Date of Patent: June 26, 2012
    Assignees: Phoenixbio Co., Ltd., Biointegrence Inc.
    Inventors: Koei Toyoshima, Mikaru Matsunaga, Katsutoshi Yoshizato

  • Hair growth method
    Publication number: 20100166719
    Abstract: A method of enabling effective hair growth and furthermore, inducing hair growth closely similar to the natural hair state in the case of transplanting dermal papillae or cultured dermal papilla cells into the skin to regenerate the hair, characterized by comprising transplanting a composition containing the following components into an epidermis defect site: (a) dermal papillae or dermal papilla cells, (b) an epidermal tissue or epidermal cells and/or (c) a tissue constituting hair follicles or cells thereof.
