Abstract

The invention specifically relates to a cosmetic preparation prepared from human umbilical cord mesenchymal stem cell-derived exosomes, belonging to the field of biological medicine. The cosmetic preparation comprises freeze-dried powder of human umbilical cord mesenchymal stem cell-derived exosomes, glycerin and aloe juice in a weight ratio of 1: 1: 10-20. A preparation method for the cosmetic preparation comprises the following steps: weighing the human umbilical cord mesenchymal stem cell-derived exosomes, glycerin and aloe juice in proportion, then carrying out mixing under stirring until a transparent mixture is obtained, and subjecting the mixture to filtering with a 0.45-[mu]m microfiltration membrane and then to filtering with a 0.22-[mu]m microfiltration membrane so as to obtain the cosmetic preparation. According to the invention, the novel human umbilical cord mesenchymal stem cell-derived exosomes are used as an active component for preparation of the cosmetic preparation with obvious effect; and the cosmetic preparation can overcome the problem of skin aging of people and has good market prospects and application value.

Description

technical field [0001] The invention belongs to the field of biomedicine, and in particular relates to a cosmetic preparation of exosomes derived from human umbilical cord mesenchymal stem cells. Background technique [0002] In 2013, three scientists from the United States and Germany won the Nobel Prize in Physiology or Medicine for their discovery of the regulation mechanism of cell vesicle transport. Exosomes, as an important class of vesicles in the human body, have also begun to receive more and more attention. Scientists have found that exosomes are involved in important biological processes such as immune response, apoptosis, angiogenesis, inflammation, and coagulation. Cells secrete some signaling molecules to distant tissues or cells by secreting exosomes. in order to play a regulatory role. [0003] In 2016, Xu Wenrong and others from Jiangsu University School of Medicine in China found that the proteins contained in exosomes derived from human umbilical cord me...
