Fig. 2. Gli and Gli2 are expressed in specific cell types in the cerebellum. Expression of Gli and Gli2 co-localize with BLBP, a marker for Bergmann glia (A,D). Purkinje cells, marked with Calbindin, do not express Gli and a few express Gli2 (B,E). Gli expression is restricted to the proliferative GCPs. The inner EGL and IGL, marked by NeuN, do not express Gli at high levels (C). However, Gli2 expression is observed throughout the EGL and IGL (F). Bars indicate layers containing Bergmann glia nuclei (BG) in (A,D), Purkinje cell layer (PCL) in (B,E) and IGL (C,F). Scale bar: 50 µm.
