Fig. 2. Niche-specific spatial transcriptional programs and their relationship to subclonal architecture.

Fig. 2

a Heatmap of horizontally integrated spatial transcriptional signatures/modules expressed in all malignant spots (n = 19,767). The sample identify for each spot is shown by different colors in the top bar. b Heatmap of GWR-based, spatially weighted correlation of the 48 spatial cluster signatures, marked by different colors on the left. Hierarchical clustering confirmed 4 clustered programs that correspond to the four modules in a, marked by different colors on the top. c The percentages of cluster signatures per tumor type contributing to each program are shown. d Representative examples of the correlation between the module gene expression and the histopathology of glioma niches across all samples (n = 10). e Heatmap of spatial weighted correlation between our modules and Ravi et al.33 modules across all malignant spots (n = 19,767). Correlation and P values were determined by non-parametric Spearman’s correlation test, Bonferroni-corrected for multiple comparisons. Source data are provided as a Source Data file, and individual P values are included. f Dot plot indicating subclonal distribution across different glioma niches marked by transcriptional modules from all subclones (n = 24). Dot size and color reflect the percentage.
