🌍 We used the first, to our knowledge, Visium HD dataset from human gut tissue in GVHD—2µm resolution—to show that CD8⁺ effector T cells cluster near intestinal stem cells in Severe GVHD and are enriched in crypt loss region, suggesting these effector cells drive tissue damage.

🧠 Key finding:
👀 Here’s the Decipher map showing clonal trajectories across tissue compartments. We discovered that cytototix CD8⁺ T cell clones are clonally expanded, change state as they move between gut layers, and acquire resident memory (Hobit⁺ Trm) phenotypes.

📈 DecompTCR uncovers which clones persist, expand, and associate with GVHD severity.

🧪 We developed StarfyshHD, a spatial transcriptomics analysis tool tailored for Visium HD data to integrate multiple samples, map fine-grained cell states, and identify spatial hubs (unique composition of cell types).

💡 It’s not just infiltration—T cells adapt and shift phenotype as they migrate through tissue.
