Stromal control of sympathetic rewiring in metastatic lymph nodes

Metastatic lymph nodes (LNs) are dynamically remodeled tissues, but this process has been understood mainly in immune and stromal terms. We show that tumor-driven LN remodeling also involves adaptive neural rewiring. In a mouse model of nodal metastasis, sympathetic fibers, but not sensory fibers, progressively expanded during LN remodeling and tracked with metastatic progression. Fibroblastic…
