TMEM119 and glioblastoma: Spearman correlation to embryonic (E17), postnatal and adult Tmem119 positive and negative microglia and LPS-stimulated adult microglia show that the EdU+ microglia population is less related to embryonic, postnatal (Tmem119+ and Tmem119−) and adult (LPS-stimulated and control) microglia than EdU– microglia (Fig. 3f), suggesting that cycling microglia in GBM adopt a transcriptome that is different from noncycling (EdU–) microglia, the latter seemingly adopting a proinflammatory polarization.
