Immunofluorescence for RPC transcription factors and cell cycle regulators in Müller glia during development. (A) Lhx2+ cells at P4 are mostly phospho-pRb (pRb) + RPC while those after P7 are pRb− Müller glia. (B) Pax6 immunoreactivity in Lhx2 + RPC and Müller glia (arrows). (C) Vsx2 immunoreactivity in Sox9 + RPC and Müller glia (arrows). (D) Nfia immunoreactivity in Lhx2 + RPC and Müller glia (arrows). (E) Cyclin D1 immunoreactivity in Lhx2 + RPC and Müller glia. (F) Cyclin D3 immunoreactivity in Lhx2 + RPC and Müller glia. NBL neuroblastic layer, GCL ganglion cell layer, ONL outer nuclear layer, INL inner nuclear layer. Scale bar = 20 µm.
