Schematic of the ‘IM-rich subset’ of lung squamous carcinoma. TNFα activation of the canonical NFκB leads to LUSC cell secretion of chemo-attractant CCL2, which stimulates the bone marrow to release inflammatory monocytes (IMs) into circulation. The IMs bring large payloads of FXIIIA into the tumor microenvironment, leading to cross-linked fibrin, LUSC invadopodia formation and progression
