Cell Proliferation High-Content Screening on Adherent Cell Cultures.
COMPUTER OPTIMIZED MICROSCOPY: METHODS AND PROTOCOLS(2019)
Abstract
Pulse-chase experiments using 5-bromo-2'-deoxyuridine (BrdU), or the more recent EdU (5-etynil-2'-deoxyuridine), enable the identification of cells going through S phase. This chapter describes a high-content proliferation assay pipeline for adherent cell cultures. High-throughput imaging is followed by high-content data analysis using a non-supervised ImageJ macroinstruction that segments the individual nuclei, determines the nucleoside analogue absence/presence, and measures the signal of up to two additional nuclear markers. Based upon the specific combination with proliferation-specific protein immunostaining, the percentage of cells undergoing different phases of the cell cycle (G0, G1, S, G2, and M) might be established. The method can be also used to estimate the proliferation (S phase) rate of particular cell subpopulations identified through labelling with specific nuclear markers.
