Fig. 6. Ectopic Hh pathway activation restores cell cycle gene expression and
bipolar cell development in retinal explants from
-Cre;Shh/c mice. Retinal explants from
wild-type and
-Cre;Shh/c mice at P1 were
cultured for 2 (A-L) or 9 (M-X) days and processed for in situ hybridization
to detect mRNA for Gli (A-D), cyclin D1 (E-H) and Chx10
(I-L) or stained for Hoechst to reveal nuclei and anti-PKC (M-P), anti-CRALBP
(Q-T) and anti-syntaxin (U-X) antibodies. The peripheral region of the
explants is shown in these panels. Scale bar: 100 µm.
