Spatial RNA profiling methods provide insight to the cellular heterogeneity and spatial architecture of complex, multi-cellular systems. Combining molecular and spatial information provides important clues to study tissue architecture in development and disease. Here, we present a comprehensive do-it-yourself guide to perform such experiments at reduced costs leveraging open-source approaches. This guide spans the entire life cycle of a project, from its initial definition to experimental choices, wet lab approaches, instrumentation and analysis. As a concrete example, we focus on Tertiary lymphoid structures (TLS), which we use to develop typical questions that can be addressed by these approaches.

Matching journals

"Similar papers" are the closest papers from that journal in the model's embedding space. They show what the match is built on, but the ranking comes mostly from a classifier over the whole training set, not from these examples alone.
