Connectogenomics: edges-first spatial biology

Spatial omics maps cell types and spatial context together. Current methods fall into two streams: mapping coordinates (where things are) and measuring connections between cells that are in contact or close proximity. We introduce the term connectogenomics as a practical umbrella for sequencing assays that directly record such contacts as a network. Combining coordinates with measured contacts lets us verify whether apparent neighbors truly interact and turn network features - such as contact density or hub centrality - into quantitative readouts. We propose a framework with four complementary tiers and a feedback loop: directly measured molecular contacts can validate coordinate-based analyses, while coordinate maps guide where to prioritize contact measurements. We illustrate this approach in cancer immunotherapy, development, and pooled genetic screens.
