TMEM119 and neoplasm: No significant differences were found between control and KLF4 knockout (KLF4-KO) mice for either the percentage of tumour area showing overall macrophage/microglia infiltration (F4/80 staining) or, specifically, microglial infiltration/activation (TMEM119+F4/80+) or BDM infiltration (TMEM119-F4/80+; Figure S5).
