Shh-expressing cells in the young adult mouse brain labeled by ShhCreER-tdTomato line treated with TAM at P30-P35 age
tdTomato + cells at 25 days post TAM depicting Shh-expressing cells at P30-P35 stage are observed in (A–D) cortical PV + neurons and (E–G) striatal PV + neurons, but not CHAT + neurons. tdTomato + cells are also observed in (H–K) MS/VDB neurons but mostly not in CHAT + cholinergic neurons. tdTomato + neurons are also present in the SN (NeuN+, image not shown) but are not colocalized to TH + DA neurons (M and N). Consistent with this data, tdTomato + neuronal terminals in the PFC (O) and STR (P) do not colocalize with TH + fibers. Scale bar = 50um).
