Claims24
A culture vessel for culturing a cell aggregate, comprising:
- a plate body having a plane;
- a plurality of wells each having an opening formed at the plane of the plate body and a culture space configured to store a cell aggregate and culture fluid;
- a plurality of tubular bodies formed on the plane of the plate body such that each of the plurality of tubular bodies is attached to and projecting upward from the plane of the plate body and has an inner cavity communicating with the culture space of a respective one of the plurality of wells through the opening;
- and
- a side wall formed on the plate body and positioned outside the plurality of tubular bodies such that the side wall is projecting upward from the plane of the plate body and surrounding the plurality of wells,
- wherein each of the plurality of tubular bodies has a tubular wall having at least one communication portion such that the at least one communication portion forms at least one communication opening through which the culture fluid is discharged from the plurality of tubular bodies into a space formed between the plurality of tubular bodies and a space formed between the tubular wall and the side wall without allowing passage of the cell aggregate, and that the at least one communication opening has one end at the plane of the plate body.
