Abstract
Source: Dillard, P., et al. A Spheroid Killing Assay by CAR T Cells. J. Vis. Exp. (2018).
Spheroids are a type of 3D cell culture model used to more accurately represent a cell’s environment compared to 2D cell culture monolayer models. In the example protocol, we will see scientists generate spheroids from a colorectal cancer cell line and apply live-cell imaging to track the spheroids’ growth.
Protocol
1. Generation of Spheroids from Colorectal Cancer Cell Line Wash HCT 116 (stably transduced to express Cluster of Differentiation 19 (CD19) and Green Fluorescence Protein (GFP)) cell monolayers with phosphate buffered saline (PBS; 5 mL for a 25 cm2 or 10 mL for a 75 cm2 flask). Add trypsin (0.5 mL for a 25 cm2 or 1 mL for a 75 cm2 flask) and incubate cells at 37 °C for 5 min. Check cell detachment under a microscop…
