  • Application of transgenic stem cell-derived exosome in preparing medicament or whitening cosmetic
    Patent number: 11761002
    Abstract: An application of a transgenic stem cell-derived exosome in preparing a medicament or whitening cosmetic is provided. In the present disclosure, miR-27b-3p is transfected into an epidermal stem cell, and a transgenic stem cell-derived exosome is harvested. It is experimentally verified that the exosome can inhibit the expression of PIK3R3 protein in melanocytes and the proliferation and migration of melanocytes; and safety experiments further demonstrate the safety of the exosome. Therefore, corresponding medicaments or cosmetics prepared from the exosome have excellent medicinal and cosmetic application prospects.
    Type: Grant
