Cancer-associated thrombosis is unaltered in the pulmonary microvasculature and pulmonary tumors of myeloid HIF1α knockout mice. (A) Quantification of fibrin deposition and (B) microthrombi number in pulmonary microvasculature of tumor-bearing wild-type (WT) and myeloid HIF1α knockout (MC HIF1ko) mice (n = 8 per group). (C) Quantification of tumor fibrin deposition in WT and MC HIF1ko mice (n = 8 per group).
