Schematic overview of NEP analysis steps (Neighborhood definition, Quantification and NEP score) and the systematic method performance comparison using simulated data for cohort distinction.

Ever wondered how to best quantify cell-cell neighbor preferences in tissues?
We compared 9+ neighbor preference (NEP) methods for analysing spatial omics data and propose a novel approach that combines the most relevant analysis features which we call COZI π¬β¨

Visualising the impact of wounding on cancer cells and the tumor microenvironment at single-cell resolution in situ!
Happy to share updated paper with new spatial transcriptomics of human skin tumors using CosMx 6'000-gene panel. All data and code are available.

Thrilled to share LUNAπ β our new generative AI model that reassembles tissue structures from dissociated cells! LUNA learns spatial priors over existing spatially resolved datasets with the aim to predict cell locations de novo.
