0Starfysh is a sophisticated computational toolbox designed to analyze spatial transcriptomics (ST) data by integrating it with histological images. Unlike existing methods that require separate single-cell RNA sequencing as a reference, this platform uses a deep generative model to identify distinct cell states and neighborhoods without external data. It employs archetypal analysis and known genetic markers to characterize complex tissue environments, such as the diverse regions within breast cancer tumors. By mapping these specialized niches, known as spatial hubs, the technology allows researchers to compare how different cell types interact across various patients and disease stages. Testing on metaplastic and triple-negative breast cancers revealed how metabolic changes and specific cell compositions shape the immune response in aggressive malignancies. Ultimately, Starfysh provides a scalable framework for understanding tissue organization and cellular communication in both healthy and diseased states.
