Cell Death Analysis in Cancer Spheroids from a Microfluidic Device

Julie Lafontaine et al. Methods Mol Biol. 2022.

Abstract

Microfluidic technology facilitates the generation of 3D spheroids from cancer cells, a more suitable model for preclinical therapeutic studies. This system opens the possibility to test many drugs combination at a low cost. Here we describe the use of microfluidic devices for cytotoxicity evaluation on cancer spheroids for the discovery of drugs that could be used in combination with radiotherapy. Device fabrication, preparation, and seeding are also covered. Cell death arising following treatment is detected and characterized according to spheroid size, colony formation assays, and flow cytometry analysis of apoptotic marker annexin V.

Keywords: 3D culture; Annexin V; Chemotherapy; Clonogenic assay; Drug screening; ImageJ; Lab-on-chip; Microfluidic; Radiotherapy; Spheroids.
