B Ferrous iron was measured in human M1- and M2-like tumor-associated macrophages. C The sorting strategy of murine M1 and M2-like tumor-associated macrophages from HCC tissues. D Ferrous iron was measured in murine M1- and M2-like tumor-associated macrophages. Data from B and D were analyzed using paired t-test, **p < 0.01, ***p < 0.001
