🛡 Architecture of the Fibrotic Bunker

Deploying spatial transcriptomics via 10x Genomics Visium, scientists discovered that quiescent tumor cells actively synthesize TGF-β and PDGF-BB morphogens, forcing local cancer-associated fibroblasts to weave a rigid type-I collagen protective capsule.

This physical armor is 3.8x denser than physiological connective tissue. It establishes a hypoperfused micro-domain that completely excludes monoclonal antibodies, antibody-drug conjugates, and cytotoxic CD8+ T cells.
