The application belongs to the field of biological medicine research and development, and particularly relates to application of umbilical cord mesenchymal stem cell-derived vascular endothelial precursor cells in preparation of medicines for preventing and treating atherosclerosis. By interfering with expression of related factors in a pyroptosis inflammatory signaling pathway of NLRP3, ASC, Caspase-1, GSDMD, IL-1β and IL-18 at a transcription and protein level, the serum triglyceride concentration, total cholesterol concentration and low-density lipoprotein concentration can be reduced, the serum oxidized low-density lipoprotein and oxygen free radical concentration can be reduced, the serum high-density lipoprotein concentration can be increased, and the atherosclerotic plaque area can be reduced and cell apoptosis in the atheromatous plaque can be inhibited.

Human corneal endothelial cells and / or human corneal endothelial precursor cells are preserved with a high survival rate of these cells being maintained, and the occurrence rate of contaminated cells in post-preservation culturing is suppressed. A storage method of human corneal endothelial cells and / or human corneal endothelial precursor cells is characterized in that human corneal endothelial cells and / or human corneal endothelial precursor cells that have been cultured using a culture medium that contains a ROCK inhibitor, and in which the content of epidermal growth factor (EGF) is less than a concentration that will cause a transformation are harvested at a timing when any one of or a plurality of the conditions (a)˜(d) have been met, and are placed in a suspension state and then preserved.
