Extended Data Fig. 2: Marker gene expression across species.
From: Innovations present in the primate interneuron repertoire

a, Examples of markers that are consistent, or that vary across species, within the four primary interneuron classes. Values are scaled UMI counts per 100,000 transcripts. b, Triple smFISH characterization of IQGAP2, PVALB and VIP in mouse (n = 1 biological replicate) and marmoset (n = 1 biological replicate) cortex. Arrows indicate double-positive cells (either IQGAP2+PVALB+ or IQGAP2+VIP+). Scale bar, 10 μm.
