  • Publication number: 20240180971
    Abstract: The present invention provides an excellent composition for therapeutically treating a skin disease (e.g., a drug, a quasi-drug or a cosmetic). The composition for therapeutically treating a skin disease according to the present invention contains exosomes secreted from stem cells (for example, adipose-derived stem cells), in which the stem cells contain drug-encapsulating nanoparticles comprising a drug (for example, statin, estrogen, retinoic acid and ascorbic acid) encapsulated in nanoparticles containing a bioabsorbable polymer.

  • Publication number: 20210038725
    Abstract: A statin-encapsulated nanoparticle contains a bioabsorbable polymer and statin encapsulated in the nanoparticle. Suitable bioabsorbable polymers include a polylactic acid (PLA) polymer or a polylactic acid-glycolic acid (PLGA) copolymer. The statin-encapsulated nanoparticle can be used to enhance the function of a stem cell. The stem cell can be a stem cell for treating an inflammatory disease.

  • Patent number: 10278926
    Abstract: A preparation containing a statin-encapsulated nanoparticle obtained by encapsulating statin in a nanoparticle containing a bioabsorbable polymer is disclosed. The nanoparticle has a number average particle diameter of less than 1000 nm. The preparation is used to enhance the function of a stem cell. A stem cell with an enhanced function is disclosed. The stem cell takes up and contains the statin-encapsulated nanoparticle.
