Figure 6. Displacement of smooth endoplasmic reticulum
Ultrastructural features of the ONL/IS interface of a control (A) and an rge/rge chick (B), at 1 day of age. A: Note the absence of endoplasmic reticulum in the perinuclear region. The bar represents 3.5 μm. B: Note the displacement of the smooth ER (marked as SER), which, in this sample, is located at the perinuclear cytoplasm of an accessory cone, internal to the level of the outer limiting membrane (dashed line). At this age accumulation of glycogen is not apparent (compare with Figure 7 and Figure 10). Müller cell microvilli are marked as "mv". The bar represents 5 μm.
