Extended Data Figure 3. Ipsilateral stimulation does not promote early tumor progression.

a. Representative Ki67 staining of CNO versus Saline versus untreated IUE-HGG sections taken from P30 tumor brains after ipsilateral stimulation. b. Representative images of corpus callosum cut tumors stained for Ki67 (quantification in main figure). Tumor samples were prepared as described above, using native GFP to image tumor. c. Representative images of Rasgrf2-dCre tumors stained for Ki67 (quantification in main figure). Tumor samples were prepared as described above, using native GFP to image tumor). Tumor sections were imaged and quantified for each condition from at least five mice to ensure reproducibility (a-c).
