  • Patent number: 10471097
    Abstract: The present invention relates to hyaluronic acid-rich node and duct system (HAR-NDS)-derived stem cells, a method for separating the same, and a use thereof and, more specifically, to node and ductal stem cells (NDSCs), which are adult stem cells having an ability to differentiate into HAR-NDS-derived neural cells, and hematopoietic stem cells having an ability to differentiate into blood cells. The present invention is capable of separating, from HAR-NDS, adult stem cells NDSCs and hematopoietic stem cells, which are not easy to obtain from bone marrow, peripheral blood and umbilical cord blood (cord blood), as an alternative source, and thus can be usefully used for treatment of brain diseases, neurological diseases, chronic infectious diseases, cancers, autoimmune diseases, organ regeneration treatments and various intractable diseases.

  • Publication number: 20180057793
    Abstract: Provided is a method for isolating and proliferating autologous cancer antigen-specific CD8+T cells, and more particularly, a method for selecting an epitope recognized by CD8+ T cells from autologous cancer antigens present in blood of individual cancer patients; and isolating autologous cancer antigen-specific CD8+ T cells by using a peptide of the selected epitope, and a method of massively proliferating CD8+ T cells by using the method. According to the present invention, it is possible to isolate autologous cancer antigen-specific CD8+ T cells by using the peptide of the CD8 T cell epitope of the autologous cancer antigen present in blood of individual cancer patients instead of a heterologous antigen. Therefore, by using T cells recognizing the autologous cancer antigen, it is possible to effectively select and eliminate cancer cells derived from the cancer patient's own cells. Thus, T cells can be applied to treatment and alleviation of cancer diseases without side effects.
