AIMP2 and glioblastoma: To determine the cell type specificity of AIMP2 expression, we compared its expression levels across key GBM cellular subtypes—MES like, AC like, oligodendrocyte progenitor cell like, and neural progenitor cell like—in both the spatial transcriptomic dataset and a separate concatenated single-cell RNA-seq cohort comprising three independent GBM datasets (Fig. 6bi, ii).
