Abstract: A method for stably amplifying a pluripotent stem cell comprises the following steps: (a) a cell implantation step: implanting pluripotent stem cells directly into a porous scaffold such that the porous scaffold contains 1×104 or more of the pluripotent stem cells; and (b) a cell amplification step: immersing the porous scaffold in a specific culture medium which is xeno-free (XF) and performing amplification culture at an ambient temperature of 35.5-39.5° C. and a CO2 concentration of 5% to obtain the amplified pluripotent stem cells, wherein the amplified pluripotent stem cells aggregate to present an embryoid body state. The amplification method of the present disclosure can easily obtain an excellent effect of increasing an amplification multiple of the pluripotent stem cells to about 3 times or more.
