  • Medium composition for rejuvenating stem cells
    Patent number: 9708584
    Abstract: The present invention relates to a medium composition for transforming stem cells from an aged person into young stem cells, and more particularly to a medium composition for culturing stem cells, which is used to rejuvenate stem cells from an aged person so as to have characteristics similar to those of the stem cells of young people, and to a method for rejuvenating stem cells, which comprises culturing stem cells from an aged person in the medium composition. According to the present invention, even mesenchymal stem cells collected from over 60 years old patients can be transformed into young mesenchymal stem cells having high differentiation ability, high telomerase activity, and high ability to express stem cell markers. Thus, the present invention can significantly increase the efficacy of cell therapy employing mesenchymal stem cells.

  • Cellular therapeutic agent for incontinence or urine comprising stem cells originated from decidua or adipose
    Patent number: 9211306
    Abstract: The present invention relates to a cellular therapeutic agent for treating urinary incontinence, and more particularly to a cellular therapeutic agent for treating urinary incontinence, which contains stem cells derived from the decidua of the placenta or menstrual fluid or stem cells derived from adipose. The decidua-derived stem cells or adipose-derived stem cells show the effects of increasing leak point pressure and urethral sphincter contractility, and thus are useful as an agent for treating urinary incontinence.

  • CELLULAR THERAPEUTIC AGENT FOR INCONTINENCE OR URINE COMPRISING STEM CELLS ORIGINATED FROM DECIDUA OR ADIPOSE
    Publication number: 20110059052
    Abstract: The present invention relates to a cellular therapeutic agent for treating urinary incontinence, and more particularly to a cellular therapeutic agent for treating urinary incontinence, which contains stem cells derived from the decidua of the placenta or menstrual fluid or stem cells derived from adipose. The decidua-derived stem cells or adipose-derived stem cells show the effects of increasing leak point pressure and urethral sphincter contractility, and thus are useful as an agent for treating urinary incontinence.

  • COMPOSITION FOR TREATING ISCHEMIC LIMB DISEASE COMPRISING STEM CELLS DERIVED FROM ADIPOSE TISSUE
    Publication number: 20100196329
    Abstract: Disclosed herein is a cell therapeutic composition for treating ischemic limb diseases, more specifically, disclosed is a cell therapeutic composition for treating ischemic diseases, which contains adipose tissue-derived mesenchymal stem cells and sucrose or mannose as an excipient. The composition induces angiogenesis around closed blood vessels in the ischemic limb lesions, and thus is useful to treat ischemic diseases.
