| titleOfInvention | Preparation method and use method of human mesenchymal stem cell exosome freeze-dried powder |
| abstract | The invention provides a preparation method and a use method of human mesenchymal stem cell exosome freeze-dried powder, which are used for solving the problems of small quantity, poor quality and low efficiency of exosome separation and recovery, and the preparation method of the human mesenchymal stem cell exosome freeze-dried powder comprises the following steps: 1) culturing, purifying and passaging the human mesenchymal stem cells; 2) inducing human mesenchymal stem cells to synthesize and secrete a large amount of functional exosomes; 3) carrying out ultrafiltration concentration on the human mesenchymal stem cell exosome to prepare a concentrated culture solution and refrigerating the concentrated culture solution; 4) the refrigerated concentrated culture solution is prepared into lyophilized powder, and the compound solution is added into the lyophilized powder for storage, so that the preparation method can effectively induce mesenchymal stem cells to synthesize and secrete exosomes to the maximum extent, is favorable for obtaining the active ingredients on a large scale, and is convenient for being directly used in large-health aspects, such as diagnosis and treatment of diseases and cosmetic plastic of human bodies. |
