  • 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: 20120276044
    Abstract: The present invention relates to the ability of adipose tissue-derived adult stem cells to migrate, and more particularly to the novel use of adipose tissue-derived adult stem cells primed with a specific chemokine or growth factor and their specific secretory products, which more effectively migrate to a disease site in vivo. The inventive composition containing either adipose-derived adult stem cells or adipose tissue-derived adult stem cells primed with a specific chemokine or growth factor can be administered by a simple method such as intravenous administration and are able to induce the targeting of the stem cells to a disease site. Thus, the composition is useful as a cell therapeutic agent.

  • 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: 20100287635
    Abstract: Disclosed herein are a cloned canine and a production method thereof. The method comprises the steps of enucleating the oocyte of a canine to prepare an enucleated recipient oocyte, conducting nuclear transfer into the enucleated oocyte using a canine somatic cell as a nuclear donor cell under optimized conditions so as to prepare a nuclear transfer embryo, and transferring the nuclear transfer embryo into the oviduct of a surrogate mother. The present invention provides a method for producing cloned canines and thus, can contribute to the development of studies in veterinary medicine, anthropology and medical science such as the propagation of superior canines, the conservation of rare or nearly extinct canines, xenotransplantation and disease animal models.
