  • Patent number: 8455251
    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.

  • Publication number: 20120263685
    Abstract: The present invention relates to a composition for preventing or treating cancer, which contains one or more selected from the group consisting of human adult stem cells and their secretory products, and to a method of preventing or treating cancer using the same. Particularly, the invention relates to the use of adult stem cells that exhibit the effect of preventing or treating cancer by activating the immune system. The human adult stem cells of the invention are administered by a simple method such as intravenous injection and are highly valuable as a cell therapeutic agent for treating various cancer (tumor) diseases. Thus, the adult stem cells will be highly useful in anticancer studies.

  • Publication number: 20110250226
    Abstract: A composition for promoting the proliferation of hematopoietic stem cells, which contains mushroom extracts, and more particularly to a composition and functional food for promoting the proliferation of hematopoietic stem cells, which contain, as active ingredients, an Inonotus Obliquus extract, a Ganoderma Luciderm extract, a Phellinus Linteus extract, and plant extracts promoting the immune activity-enhancing effects of these mushroom extracts. The composition and functional food assists in enhancing immune activity by significantly promoting the proliferation of hematopoietic stem cells, and shows positive effects on the increase in anticancer activity, anti-inflammatory activity and cell activity, the regeneration of damaged tissue and the prevention of cardiovascular diseases, through the proliferation of hematopoietic stem cells and the enhancement of immune activity.
