Abstract

This video demonstrates a method to establish a three-dimensional tumor spheroid and T cell co-culture. An agarose cast with microwells containing tumor spheroids is prepared, followed by the addition of T cells. After incubation, this setup allows studying the interaction of T cells with tumor spheroids in a controlled three-dimensional environment.

Protocol

1. Generation of spheroids Prepare and autoclave 2% agarose in 1x phosphate-buffered saline (PBS) (e.g., 1 g agarose in 50 mL of 1x PBS) and autoclave 35- and 81-microwell rubber molds. CAUTION: Avoid using low-melting agarose for generating the agarose casts for immunohistochemistry (IHC) processing. Prepare agarose casts NOTE: 35-microwell casts are used for invasion, immunofluorescence (IF) and cell isolation assays. 81-microwell ca…
