Scherer's map, remapped.

Spatial RNA and protein profiling of IDH-mutant gliomas reveals hypoxia and necrosis as key organizers of expansive growth and white-matter tracts as invasion guides.

• Why it matters: Understanding the mechanisms behind glioma growth patterns is crucial for developing targeted therapies, especially given the longstanding importance of Scherer's classification in neuro-oncology.
• What they did: Hoefflin et al. employed spatial RNA and protein profiling techniques on IDH-mutant gliomas to identify how hypoxia, necrosis, and white-matter tracts influence tumor expansion and invasion.
• The result: The findings clarify the spatial organization of glioma growth, enabling more precise targeting of tumor microenvironments and potentially improving treatment strategies.
