  • Method for preparing composition for promoting hair growth using Nanog-introduced mesenchymal stem cells derived from fetus in amniotic fluid
    Patent number: 10640541
    Abstract: The present invention relates to a culture solution of MSCs derived from a fetus in amniotic fluid, and more specifically, to a composition for promoting hair growth or preventing hair loss, which includes a culture solution of MSCs overexpressing a reprogramming factor Nanog and derived from a fetus in amniotic fluid as an active ingredient. In addition, the present invention relates to a method for preparing the composition, which includes culturing Nanog-introduced MSCs derived from a fetus in amniotic fluid in a conditioned medium and collecting the culture solution. The conditioned medium composition according to the present invention exhibits a hair growth promoting effect, and thus is able to be used as cosmetic and pharmaceutical compositions for promoting hair growth.
