Fig. 7. The gene expression landscape of 420 putative brain cell type signature
genes in cerebral cortex.(A) The expression variation for the 420 signature
genes in the different brain regions was analyzed on the basis of the coefficient
of variation (CV) of NX values across the 10 regions (see figs. S33 and S34
for expression heatmap and scatterplot across the 10 regions). (B)Theexpression
levels for the individual signature genesin the different tissue types. The most
abundant genes are indicated by gene names (see fig. S32 for expression
heatmap of the signature genes across all tissues). (C) Chord diagram shows
the tissue specificity of brain cell type signature genes. Each link represents the
number of cell type signature genes that are elevated at a tissue level in the


analyzed organ and tissue types. (D) Examples of signature genes and their
protein localization in the different cell types. Microglia signature genes
(ALOX5, ITGB2, and PYCARD) are highly expressed in spleen. Several astrocyte
signature genes, including SLC13A5 and ALDH1L1, have elevated expression in
liver, whereas SNTA1 is highly expressed in skeletal muscle. Neuronal examples
(KCNAB2, KCNB1, and PDE1B) are located in neuronal cell bodies in the brain,
while oligodendrocyte proteins, including MAG, are detected in white matter of
the brain as well as in smooth muscle (PPP1R14A) and renal tubule of kidney
(ENPP6). More detailed expression profiles for all cell signature genes are shown
in figs. S33 to S35. Scale bars, 25mm.
