Begin with a culture plate containing an agarose cast. The cast comprises a seeding chamber with multiple microwells.
Each microwell contains a tumor spheroid in a culture medium. The spheroids are three-dimensional aggregates of tumor cells.
First, remove the medium surrounding the agarose cast. Then, remove the medium within the cast from one corner of the seeding chamber to avoid the loss of spheroids.
Introduce a suspension of tumor-specific T cells dropwise into the seeding chamber, allowing the cells to settle into the microwells containing the spheroids.
Next, add a culture medium around the agarose cast and incubate the plate under physiological conditions to develop a co-culture.
During incubation, the T cells surround the spheroid. A subset of T cells infiltrate the spheroid, while others remain in the periphery, establishing a three-dimensional co-culture model.
