was highly enriched with markers of astrocytes (Table 1), were AHCYL1, AHCYL1, NTRK2, SOX9, PDLIM5, PPAP2B, PLSCR4, TP53BP2, METTL7A and NTRK2 (Supplementary Table 9). Notably, these genes showed higher average membership than many genes that are considered to be canonical markers of astrocytes, including SLC1A3 (15th), GJA1 (17th), GLUL (56th), and GFAP (82nd). The ten genes with the highest average membership for M16, which was enriched with markers of neurons and synaptic proteins (Table 1 and Supplementary Table 7), were PREPL, SYNJ1, TPD52, G3BP2, YWHAZ, PAFAH1B1, GABRG2, SCAMP1, ANK2 and GLRB (Supplementary Table 9). For some of these genes (for example, PREPL and TPD52), no specific association with neuronal function has previously been reported, to the best of our knowledge.
