A mesonephric stem cell line is provided to be differentiated into various cells, treat various diseases or disorders through cell therapy and be used for developing a transgenic animal used for xenotransplantation. A method for preparing a mesonephric stem cell line comprises the steps of: (a) obtaining a mesonephric stem cell from mesonephros of mammal; (b) culturing the mesonephric stem cell onto a feeder cell layer to form a colony; and (c) subculturing the colony to obtain the mesonephric stem cell line, wherein the mammal is human, pig, cattle, sheep, horse, rabbit, goat, mouse, hamster or rat and the feeder cell layer is a fibroblast layer. A mesonephric stem cell line is derived from the mesonephros of the mammal and is characterized in that it show a positive reaction regarding alkaline phosphatase and has the ability of being naturally differentiated into embryonic bodies. Further, the fibroblast is derived from ICR mouse, and a number of the fibroblast is 1.8 to 2.8x10^5 cell/ml. |
