  • Patent number: 11883438
    Abstract: It is an object to provide a technique useful for embryo transfer and development of reproductive medical care. Provided are a sperm activator containing a disrupted product of one or more cells selected from the group consisting of adipose tissue-derived stem cells, dental pulp-derived stem cells, bone marrow-derived stem cells, and umbilical cord blood-derived stem cells as an active ingredient, and an artificial insemination method utilizing the same.

  • Publication number: 20220387507
    Abstract: The purpose of the present invention is to provide a novel medical application using pluripotent stem cells in regenerative medicine. The present invention provides a cell formulation and pharmaceutical composition that are for amelioration and therapy for frequent urination and bladder pain caused by the inflammation of the bladder and that contain SSEA-3 positive pluripotent stem cells isolated from cultured mesenchymal cells or a mesenchymal tissue of a living organism. The cell formulation according to the present invention is considered to be based on a mechanism in which, for example, Muse cells are administered against interstitial cystitis having the abovementioned disorders to be successfully engrafted into affected bladder tissue, whereby the disorders are ameliorated and treated.

  • Publication number: 20140314724
    Abstract: An object is to provide a novel medical use of adipose tissue-derived mesenchymal stem cells. It was discovered that adipose tissue-derived mesenchymal stem cells (ASC) promote improvement of erectile dysfunction and recovery of the urge to urinate (improvement of sensory disorders of the lower urinary tract). On the basis of the discovery, a cell preparation containing adipose tissue-derived mesenchymal stem cells, which is effective to erectile dysfunction or sensory disorders of the lower urinary tract, is provided. In one embodiment, adipose tissue-derived mesenchymal stem cells and body fat are used in combination.

  • Publication number: 20100092432
    Abstract: [Problems] To provide a novel use of multipotential stem cells originating in a fat tissue. [Means for Solving Problems] It is intended to provide a cell preparation which contains multipotential stem cells originating in a fat tissue and is usable for an ischemic disease, impairment of renal function, wound, urinary incontinence or osteoporosis. As the multipotential stem cells originating in a fat tissue, use is made of cells which proliferate in the case of centrifuging cells separated from a fat tissue and culturing the thus sedimented cells (an SVF fraction) under low-serum conditions. In an embodiment, a cell preparation containing the SVF fraction is provided.
