Figure 4. Developmental expression of cone transducin γ protein in the embryonic and postnatal retina. Immunohistochemical staining
was performed on coronal sections starting at (A) E10.5 (before cone birth) through (I) P21. Beginning at E13.5, cone transducin γ expression is observed in cells along the ventricular surface (arrows in D), and this expression continues through all ages tested. Scale bars = 100 µm.
