Fig. 7. Shh signalling modulates Hes gene expression in RPC. (A,B) In situ
hybridization for Hes1 mRNA in the retina of wild-type (A) and
-Cre;Shh/c (B) mice at P0. Hes1
expression is reduced in the peripheral retina of the
-Cre;Shh/c (between the red arrows). (C)
Semi-quantitative RT-PCR analysis of gene expression in control E18 retinas
and in E18 retinal explants cultured for 1 and 3 days under the indicated
conditions. Scale bar: 100 µm in A,B.
