Image-based high-throughput mapping of TGF-β-induced phosphocomplexes at a single-cell level

Abstract

To improve our ability to monitor cellular responses to e.g. cytokines or drugs, Lönn et al have developed a semi-automated system for large-scale in situ proximity ligation assays (isPLA) in HaCAT keratinocyte cells. Their approach expands the scope for image-based single cell analyses by combining observations of protein interactions and modifications with morphological details of individual cells at high throughput.
