New LATTICE framework integrates multimodal spatial omics data

Researchers have developed LATTICE, a novel graph-based self-supervised learning framework designed to integrate multimodal spatial omics data. This framework harmonizes transcriptomic and epigenomic information, creating unified representations for individual tissue spots. LATTICE utilizes a TransformerConv encoder with objectives like masked reconstruction and cross-modal alignment, demonstrating stable optimization and reproducible embeddings on a melanoma cohort. The integration of multiple omics modalities significantly improved concordance with existing clustering methods and spatial contiguity, though it also captured regulatory structures beyond simple transcriptomic similarity.
