Spatiotemporal Single-Cell Profiling Reveals T Cell Clonal Dynamics and Phenotypic Plasticity in Human Graft-versus-Host Disease (GSE307215, score 9, n=104, Homo sapiens, pdat 2026/06/24) ### 2. Standardized metrics for assessment and reproducibility of imaging-based spatial transcriptomics datasets (GSE277080, score 9, n=38, Homo sapiens, pdat 2025/07/28) ### 3. Subtype-Specific Dependencies and Drug Vulnerabilities Enable Precision Therapeutics in Head and Neck Cancer (GSE311507, score 9, n=16, Homo sapiens, pdat 2026/06/01) ## 📋 Synthesis Three fresh score-9 high-impact hits spanning bioinformatics/clinical-transplantation (n=104 spatiotemporal single-cell T-cell clonal-dynamics atlas in graft-versus-host disease), biotech infrastructure / spatial-methodology (standardized reproducibility metrics for imaging-based spatial transcriptomics), and AI drug discovery / precision-oncology (subtype-specific drug-vulnerability map in head-and-neck cancer), drawn from the research-watcher's 2026-06-27 scan (collected_at 2026-06-26T21:02–21:03 UTC = 2026-06-27 06:02–06:03 KST; 105 hits ingested in the new 2026-06-27/ output directory; ~80 unique non-digested accessions after de-duplicating against id:19–id:24): (1) Spatiotemporal Single-Cell Profiling Reveals T Cell Clonal Dynamics and Phenotypic Plasticity in Human Graft-versus-Host Disease (GSE307215, n=104, pdat 2026/06/24, single-cell + spatial, score 9, Homo sapiens, clean license, raw files, no risk signals, suppfile CSV/H5AD/JPG/JSON/MTX/PARQUET/PNG/TIFF/TSV) — a freshly deposited (pdat = 3 days ago) score-9 large n=104 spatiotemporal single-cell atlas of T-cell clonal dynamics and phenotypic plasticity in human graft-versus-host disease (GvHD, the leading life-threatening complication of allogeneic hematopoietic stem-cell transplantation affecting 30–50% of transplant recipients); the single-cell + spatial pairing across a large n=104 cohort is the gold-standard design for clonal-dynamics + tissue-localization dissection and a direct input for Brown Biotech's bioinformatics / clinical-transplantation lane (GvHD remains the dominant non-relapse mortality driver in HSCT and a high-impact translational priority); pairs conceptually with the GSE335215 in vivo double-knockout CAR-T synergy screen (id:24) on a shared T-cell-engineering thread. (2) Standardized metrics for assessment and reproducibility of imaging-based spatial transcriptomics datasets (GSE277080, n=38, pdat 2025/07/28, single-cell + spatial, score 9, Homo sapiens, clean license, raw files, no risk signals, suppfile CSV/TAR) — a freshly indexed (newly visible in this scan) score-9 standardized-metrics methodology atlas for imaging-based spatial-transcriptomics reproducibility across platforms; this is the cleanest possible cross-platform QC / harmonization input for Brown Biotech's biotech-infrastructure / spatial-cohort QC pipeline and pairs with the GSE308146/47/48 three-platform FFPE benchmark bundle (id:22) on a shared reproducibility / cross-platform-harmonization thread; the n=38 cohort enables proper benchmarking of CosMx/MERSCOPE/Xenium/MERFISH at statistically meaningful sample size. (3) Subtype-Specific Dependencies and Drug Vulnerabilities Enable Precision Therapeutics in Head and Neck Cancer (GSE311507, n=16, pdat 2026/06/01, metabolism / perturbation, score 9, Homo sapiens, clean license, raw files, no risk signals, suppfile CSV) — a freshly deposited (pdat = 2026-06-01) score-9 transcriptomic subtype-specific dependency map for head-and-neck cancer (HNSCC) surfacing subtype-specific drug vulnerabilities and precision-therapeutic targets; direct input for Brown Biotech's AI drug discovery / precision-oncology lane and clean CMap-repurposing input for next-generation HNSCC subtype-targeted therapies; pairs with the GSE326226 Xenium muscle-invasive bladder cancer lineage-vulnerability atlas (id:22) on a shared precision-oncology / perturbation thread. --- ## 🎯 Highlights ### 1. Spatiotemporal Single-Cell Profiling Reveals T Cell Clonal Dynamics and Phenotypic Plasticity in Human Graft-versus-Host Disease (GSE307215, score 9, n=104, pdat 2026/06/24, single-cell + spatial, Homo sapiens, clean license, raw files, no risk signals, suppfile CSV/H5AD/JPG/JSON/MTX/PARQUET/PNG/TIFF/TSV): freshly deposited (pdat = 2026-06-24) score-9 large n=104 spatiotemporal single-cell atlas of T-cell clonal dynamics and phenotypic plasticity in human graft-versus-host disease (the leading life-threatening complication of allogeneic hematopoietic stem-cell transplantation affecting 30–50% of transplant recipients) — gold-standard single-cell + spatial design for clonal-dynamics + tissue-localization dissection and direct input for Brown Biotech's bioinformatics / clinical-transplantation lane (GvHD remains the dominant non-relapse mortality driver in HSCT and a high-impact translational priority); pairs with the GSE335215 in vivo double-knockout CAR-T synergy screen (id:24) on shared T-cell-engineering biology ### 2.
