(A) VZ born Purkinje cells expressing CTIP1 (A,C) and Calbindin (B) migrate around the RL (red arrowhead). The RL expresses classic markers like PAX6 (D), WLS (E), TBR2 (F) and LMX1A (G). (H) ATOH1 is expressed by cells exiting the RL into the external granule layer (white arrowhead). Sections were counterstained with DAPI (A-F) and Fast green (G,H). Scale bar = 100 μm (white), 500 μm (blue).
