Figure 4. SST- and PV-expressing interneuron subgroups are generated contemporaneously during development.

Figure 4

The cortex of P30 mice, exposed to BrdU at E12.5, E14.5, or E16.5 as previously published (Xu et al., 2004), was processed for immunofluorescence for BrdU and either parvalbumin (A; PV) or somatostatin (B; SST) with arrows indicating co-expression. (C) The percentages of SST/PV co-labeling with BrdU are not significantly different at any of the ages studied in either the superficial (Layers II-IV) or deep (Layers V-VI) cortex.
