  • Publication number: 20100266553
    Abstract: The present invention relates to a method for isolating and culturing adult stem cells derived from human amniotic membrane in high yield, and more particularly to a method for obtaining a large amount of adult stem cells, the method comprising obtaining amniotic epithelial cells from human amniotic tissue in high yield by treatment with dithiothreitol (DTT) and a low concentration of trypsin and culturing the amniotic epithelial cells in a medium containing a Rho-associated kinase inhibitor. The human amniotic epithelial cell-derived stem cells are easily extracted compared to existing therapeutic stem cells such as umbilical cord blood stem cells and bone marrow stem cells, the yield and proliferation thereof are significantly increased by DTT treatment, the addition of the ROCK inhibitor or the replacement of medium. Thus, the method can be used to efficiently prepare adult stem cells.

  • Patent number: 7807461
    Abstract: This invention relates to human adipose tissue-derived multipotent adult stem cells. More particularly, the invention relates to human adipose tissue-derived multipotent stem cells, which can be maintained in an undifferentiated state for a long period of time by forming spheres and have high proliferation rates, as well as methods for isolating and maintaining the adult stem cells, and methods for differentiating the multipotent adult stem cells into nerve cells, fat cells, cartilage cells, osteogenic cells and insulin-releasing pancreatic beta-cells. Also, the invention relates to cellular therapeutic agents for treating osteoarthritis, osteoporosis and diabetes and for forming breast tissue, which contain the differentiated cells or the adult stem cells.

  • Publication number: 20100189827
    Abstract: Antiviral compositions including Alnus japonica extracts are described as useful for preventing or treating diseases caused by influenza virus infection of humans and other mammalian and avian subjects (e.g., pigs, horses, birds, and the like). Alnus japonica extracts in such use exhibit low toxicity in normal cell environments, and excellent antiviral effects. Compositions and anti-viral agents for influenza virus that include Alnus japonica extracts are effectively used in foods and pharmaceutical products for preventing and treating influenza virus diseases.

  • Patent number: 7687062
    Abstract: The present invention relates to a method for diagnosing colon cancer by detecting a colon cancer specific antigen, defensin ?6 from the blood of patient and a diagnostic kit for colon cancer comprising anti-defensin ?6 antibody. The diagnostic kit for colon cancer of present invention comprises: a solid support such as 96-well plate for ELISA, nitrocellulose membrane, polyvinylidene fluoride membrane, microplate, glass substrate, polystyrene substrate, silicone substrate or metal plate, on which anti-defensin ?6 antibody is immobilized; and, a means for detecting colon cancer specific antigen such as a primary antibody which specifically binds with an antigen conjugated with an antibody on a solid substrate and a secondary antibody-signal complex which specifically binds with the primary antibody. The diagnostic kit of the invention can diagnose colon cancer with the minute amount of patients' blood, which makes possible the easy and simple diagnosis of colon cancer.

  • Publication number: 20080286243
    Abstract: The present invention relates to a method for isolating hair follicle stem cells and a composition for inducing hair growth. More specifically, relates to a method for isolating hair follicle stem cells showing a positive immunological response to CD34, by chemically degrading hair follicle-containing scalp tissue and then culturing the degraded tissue in a serum-containing medium and a serum-free medium, as well as a composition for inducing hair growth, which contains, as an active ingredient, CD34-positive hair follicle stem cells isolated by the method. The hair follicle-derived stem cells, which are obtained according to the disclosed method, are classified as autologous adult stem cells, have self-renewal capability, the ability to differentiate into adult hair follicle cells and the ability to induce hair growth, and can be used as a novel cell therapeutic agent against hair loss.
