Using Harmony, we generated a UMAP combining G-Smo, M-Smo, and WT cells, color-coded the clusters, and analyzed cluster-specific gene expression profiles; of the proliferative cell types, CGNPs and medulloblastoma cells, grouped together in a set of Barhl1+ clusters, while interneuron progenitors formed a separate group distinguished by Pax3 and Pax2 (Supplementary Fig. 2 and Supplementary Data 6). This evidence concerns the gene PAX2 and medulloblastoma.
