    Spatial Positioning and Matrix Programs of Cancer-Associated Fibroblasts Promote T Cell Exclusion in Human Lung Tumors

    It is currently accepted that cancer-associated fibroblasts participate in T cell exclusion from tumor nests. To unbiasedly test this, scientists used single-cell RNA sequencing coupled with multiplex imaging on a large cohort of lung tumors.
