Fig. 3. Normal development of ventral midbrain progenitors and Nurr1+
TH+ mDA neurons in Shhcko embryos at E12.5.
(A-H) Coronal sections of mouse embryos. (A,E) Shh expression is
missing in Shhcko embyos (E), whereas it is expressed in basal
midbrain progenitors in control embryos (A). (B-D,F-H) Similar expression of
Foxa1/2 and Nurr1 and TH in the ventral midbrain of Shhcko (F-H) and
in control embryos (B-D). Scale bars: 75 µm.
