Crafting a blueprint for single-cell RNA sequencing

Droplet-based single-cell RNA sequencing (scRNA-Seq) has moved rapidly from a technology with great potential to a method applied to ever-broader questions. The detailed information that scRNA-Seq offers has proven incredibly powerful in resolving cell responses to developmental and environmental cues. However, to maximize the potential of this technology, a panoply of upstream, practical points require consideration. Principal among these are the optimization of cell-isolation procedures, accommodating biotic/abiotic stress responses, and discerning the number of cells and sequencing reads needed. To complement reviews outlining applications and data analysis tools for scRNA-Seq, University of Tübingen researchers discuss these considerations and provide practical tips to tailor experimental design and ensure the best possible outcome.
