Figure 2. Cerebellar progenitors for Purkinje cells and Pax2 + INs.

(a–p) Lineage tracing analyses using Olig2^GFP/+ (a–d,i–l) and Gsx1^GFP/+ (e–h,m–p) embryos. (a–h) In the cerebellum, Purkinje cells are specifically labelled with an antibody for Corl2. (i–p) GABAergic interneurons are labelled with an antibody for Pax2. Arrowheads highlight double-stained cells. Stages, genotypes and antibodies are indicated. Scale bars represent (a,e,i and m) 100 μm, (b–d,f–h,j–l and n–p) 25 μm.
