NOS2 and neoplasm: GBM Brain sections parallel to the dispersed cells used in Fig. S4 from the Vehicle, CCP and CCP + IL12Ab groups were used to assess and quantify the expression of iNOS on tumor associated microglia (Iba1(+)/RM0029-11H3(−)) and macrophages (Iba1(+)/RM0029-11H3(+)) upon CCP and CCP + IL12Ab treatment.
