CD93 and glioma: We also preliminarily explored CD93 expression among different cells in various single-cell RNA-seq glioma datasets via single-cell TIME (scTIME) portal (Hong et al. 2021), Tumor Immune Single-cell Hub (TISCH) (Sun et al. 2021a), Single Cell Portal (https://singlecell.broadinstitute.org/single_cell) and Cancer Single-cell Expression Map (CancerSCEM) (Zeng et al. 2022).
