Fig. 4: VEGFA activation exhibits spatial variability within the primary tumour.

a Non-hierarchical clustering of the top 0.5% differentially expressed genes within the primary tumour ROIs, calculated by standard deviation of log2(normalised counts). b Bubble plot of VEGFA gene expression (normalised counts) represented as bubble size, overlayed on top of images from GeoMx DSP. Images are numbered as in Supplementary Fig. 1a.
