Patent ID: 10961502

Abstract:
The present invention disclosed a method for preparing of collagen having regeneration and repair effects from Wharton's Jelly mesenchymal stein cells, comprising steps of culturing the Wharton's Jelly mesenchymal stein cells in a first medium for 16 to 24 hours; replacing the first medium with a second medium for culturing the Wharton's Jelly mesenchymal stein cells for 36 to 48 hours; collecting the Wharton's Jelly mesenchymal stein cells and adding a cell lysis solution to lyse the Wharton's Jelly mesenchymal stein cells for 0.5 to 2 hours, adding an inorganic salt solution to the cell lysis solution to obtain a mixing solution for further incubation at 4° C. for 24 to 48 hours; centrifuging the mixing solution and collecting a sediment, dissolving the sediment by a preservation solution to obtain a collage.
