  • From an initial set of genes (19,369 probe sets), the GLT1+/Gfap-GFP+ astrocytic profile was compared with the Thy1-YFP+ neuronal profile and the GLT1/Gfap-GFP cell profile, respectively. The intersection (924 probe sets) of these two independent comparisons was extracted and called astrocyte-enriched genes. There was no statistical significant difference in any of the astrocyte-enriched genes between the GLT1+/Gfap-GFP+ and the GLT1+/Gfap-GFP astrocytic profiles (nonpaired Student's t test; Benjamini-Hochberg FDR correction of 5%). FD, Fold difference between GLT1+/Gfap-GFP−/+ astrocytes (n = 6) versus GLT1/Gfap-GFP cells (n = 3); Corr. p value, Nonpaired Student's t test, Benjamini-Hochberg FDR correction of 5%.
