Spatial and Single-Cell Characterization of Human Glioblastoma Tumor Microenvironment Reveals Malignant Cellular Communities
The research combined spatial transcriptomics, single‑cell RNA sequencing, scATAC‑seq and Patch‑seq from 100 glioblastoma patients, covering 121 spatial profiles. It revealed four malignant cellular communities that consistently share cell‑type composition and gene‑expression patterns. Within these, two mesenchymal‑like tumor subpopulations were defined: MES‑Hyp, which co‑localizes with hypoxic, monocyte‑derived macrophages, and MES‑Ast, which aligns with endothelial and pericyte niches. Patch‑seq demonstrated that neuronal synapses predominantly connect with oligodendrocyte‑progenitor‑like tumor cells, and the study publicly released all data and analysis code.
