    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.

    Abstract: The present invention relates to a cell differentiation medium composition, a high secretion insulin-producing cells and a preparation method thereof. The high secretion insulin-producing cells obtained by using the cell differentiation medium composition to induce stem cell differentiated under specific conditions can secrete a large amount of insulin in a short time, and when the high-secreting insulin-producing cells are transplanted into the human body, they are not easy to be swallowed by macrophages, which can improve the survival rate of the insulin-producing cells and prolong the time of insulin secretion thereby.
