Fig. 5. Notch1- RPC differentiation into precursors of
photoreceptors. The expression of factors involved in photoreceptor
differentiation Otx2 (A,C,F,H), Crx (B,D,G,I) and Thrß2 (E,J) was
analyzed by in situ hybridization on control (A-E) and
Notch1f/f;
-Cre (F-J) eyes. In the control
E13.5 (A,B) and E16.5 (C-E) retinas, the expression of
Otx2 (A,C), Crx (B,D) and Thrß2 (E) is detected in the outer neuroblastic
layer (onb). In the Notch1f/f;
-Cre
retinas, the expression of Otx2 (F,H), Crx (G,I)
and Thrß2 (J) is detected in the different layers of the
peripheral retina. le, lens; onb, outer neuroblastic layer; RPE, retinal
