Abstract: The present invention relates to a culture vessel for three-dimensional cell cultivation and a three-dimensional cell co-cultivation method using the same. The culture vessel comprises a well formed by a column positioned thereon and at least one support protruding from the column within the well. In contrast to conventional techniques, the present invention allows cells to be cultured at a position spaced from a culture vessel, thus enjoying the advantage of smoothly supplying oxygen necessary for three-dimensional cell culture structures.

Abstract: The present invention relates to an insertable culture container and a kit for three-dimensional cell culture, and a three-dimensional cell co-culture method using the same, the insertable culture container for three-dimensional cell culture comprising: a cylindrical side wall having open upper and lower portions; at least one hook protruding outward from the upper side of the side wall; and at least one support protruding inward from the lower side of the side wall. The present invention is advantageous in that air required for a three-dimensional cell culture structure can be smoothly supplied since the cell is cultured at a position spaced apart from a bottom surface of the culture container, and an existing culture plate can be used without change due to the culture container configured as an insert type.
