Kwon et al — Lymphatic Contractility and Drainage After Lymphadenectomy (Mouse Model)

Correction — see Fact-Check Log

Original note said “adequate lymph node generation happens in a month.” Lymph nodes do not regenerate once excised. What this paper shows is lymphatic vessel regeneration and co-opting of pre-existing collateral vessels/nodes, with contractile function restored within 13 days. Rephrase any mechanism paragraph to “collateral vessel recruitment,” not “node generation.”

Verified verbatim (conclusion)

Both lymphatic vessel regeneration and co-opting of contralateral vessels occur following lymphadenectomy, with contractile function restored within 13 days, providing a basis for preclinical and clinical investigations to hasten lymphatic repair and restore contractile lymphatic function after surgery to prevent cancer-acquired lymphedema. Patterns of cancer metastasis after lymphadenectomy were altered, consistent with patterns of re-directed lymphatic drainage.

My take

This is the mouse-model mechanistic backbone for “why does drainage redirect contralaterally at all” — but keep it clearly labelled as animal-model evidence, and correct the node-generation misstatement before it goes anywhere near a draft. Possible link to wound healing / immunosuppressant-driven lymphangiogenesis (VEGF-C, mast cells) as a follow-up angle, not established by this paper itself.
