High-dimensional signalling analysis of organoids

Cellular phenotypes are regulated by dynamic signalling processes that involve proteins, post-translational modifications, epigenetic events, and transcriptional responses. Functional perturbation studies are required to understand cell signalling mechanisms and organoids have recently emerged as scalable biomimetic models amenable to large-scale perturbation. Here, we review the recent advances in high-dimensional analysis of cell signalling in organoids. Single-cell technologies provide cell-type specific analysis of multiple biochemical modalities, enabling a deeper understanding of the signalling mechanisms driving cell-fate dynamics. Emerging multimodal techniques are further revealing coordination between signalling layers and are poised to increase our mechanistic understanding of cell signalling.
