Newborn MSNs do not differ from mature MSNs in their DA receptor expression. (A) Dopamine receptors were highly expressed in the MSt and Area X shown here for D1A in a non-fluorescent in situ hybridization (blue precipitate). (B–D) New MSNs (BrdU+, arrow, fluorescent green label) expressed dopamine receptor D1A (dark precipitate). (E–G) New MSNs (BrdU+, arrow) expressed DA receptor D2. (H) There was no significant difference in the expression of dopamine receptor types between older neurons (BrdU-) and 42-day-old neurons (BrdU+). One data point represents one animal. Shown are mean and SD. Scale bars: 10 μm (B–F), 500 μm (A).
