Abstract
Cortical GABAergic inhibitory interneurons have crucial roles in the development and function of the cerebral cortex. In rodents, nearly all neocortical interneurons are generated from the subcortical ganglionic eminences. In humans and nonhuman primates, however, the developmental origin of neocortical GABAergic interneurons remains unclear. Here we show that the expression patterns of several key transcription factors in the developing primate telencephalon are very similar to those in rodents, delineating the three main subcortical progenitor domains (the medial, lateral and caudal ganglionic eminences) and the interneurons tangentially migrating from them. On the basis of the continuity of Sox6, COUP-TFII and Sp8 transcription factor expression and evidence from cell migration and cell fate analyses, we propose that the majority of primate neocortical GABAergic interneurons originate from ganglionic eminences of the ventral telencephalon. Our findings reveal that the mammalian neocortex shares basic rules for interneuron development, substantially reshaping our understanding of the origin and classification of primate neocortical interneurons.

Note that a wide range overlap of SOM+, nNOS+ and CB+ cells (o). The majority of NPY+ cells expressed SOM and nNOS (p). Nearly all VIP+ cells expressed CR (t).

Supplementary Figure 12 The proportions of Sox6+, COUP-TFII+ and Sp8+ interneurons in the monkey frontal, temporal and occipital lobe are different.
(a) In 6-month-old and 17-month-old monkey brains, a higher proportion of COUP-TFII+ and/or Sp8+ interneurons was found in the frontal lobe neocortex (prefrontal cortex), while a higher proportion of Sox6+ interneurons was found in the neocortex of the temporal (lateral temporal cortex) and occipital lobe (primary visual cortex). (b–d) The percentage of different subtypes of interneurons that expressed transcription factors in the 6-month-old monkey prefrontal cortex. (e–g) The percentage of different transcription factors that expressed interneuron markers in the 6-month-old monkey prefrontal cortex. (h–j) The percentage of different transcription factors that expressed interneuron markers in the 17-month-old monkey prefrontal cortex. (k) Schematic diagram showing the origin and classification of monkey and human neocortical interneurons. We propose that the majority of neocortical interneurons in the monkey and human brain originate from the MGE, dLGE and CGE of the ventral telencephalon (see quantitative data in Fig. 5 and Fig. 6). MGE-derived neocortical interneurons (Sox6+) mainly includes PV+, SOM+, nNOS+, CB+ and NPY+ interneurons. PV+ interneurons represent a distinct subpopulation of MGE-derived neocortical interneurons, whereas SOM+, nNOS+ and CB+ interneurons largely overlap. The vast majority of NPY+ interneurons express SOM and nNOS but not CB. NPY+ interneurons strongly express SOM and nNOS, representing type I nNOS+ interneurons that have large somata. Weakly Reelin (W-Reelin)+ interneurons are derived from the MGE, which we only analyzed in the monkey neocortex. W-Reelin+ interneurons express SOM, nNOS and CB, but not NPY. A small subset of COUP-TFII+ interneurons is derived from the dorsal/caudal MGE (Sox6+). These interneurons express SOM and nNOS, but not CB or NPY. A small fraction of MGE-derived CR+/Sox6+ interneurons are present in the monkey but not human neocortex. These interneurons express SOM and nNOS, but not CB, NPY or COUP-TFII. Dorsal LGE and CGE (dLGE/CGE)-derived neocortical interneurons (COUP-TFII+ and/or Sp8+) mainly includes CR+, VIP+ and strongly Reelin (S-Reelin)+ interneurons. The vast majority of CR+ interneurons expresses COUP-TFII and/or Sp8, contributing to the largest population of dLGE/CGE-derived interneurons. Nearly all VIP+ and S-Reelin+ interneurons that express COUP-TFII and/or Sp8 but not Sox6 are derived from the dLGE/CGE. A subpopulation of S-Reelin+ interneurons and the majority of VIP+ interneurons also express CR.

This movie shows an example of one mitotic MGE cell migrating tangentially to the LGE.
GFP-expressing adenovirus (adenoGFP) was microinjected into the MGE of an E55 monkey brain slice. Time-lapse images were captured by Perkin Elmer UltraView live cell imaging system. The recording was started around 24 hours after virus injection. The recording time lasted approximately 120 hours (5 days) and the recording interval was 25 minutes. Twenty-four after virus injection, we found many GFP-labeled cells in the VZ/SVZ of the MGE and LGE. A very small number of GFP+ cells were also observed in the neocortex at this stage. Forty-nine hours after virus injection, a mitotic cell (arrows) in the MGE migrating into the LGE was observed. (MPG 13758 kb)

Twenty-five hours after virus injection, a mitotic cell (arrows) and a postmitotic cell (arrowhead) migrated tangentially from the MGE towards the LGE. Note that the postmitotic cell (arrowhead) had a leading process oriented away from the MGE. (MPG 18260 kb)
