Figure 4. An axonless A type HC in a 7 day wholemounted retina

Wholemount of a 7 day detached retina labeled as in Figure 3. The triple-labeled axonless A type HC (HA) appears bluish-white. The greenish tinge to its distal-most dendrites suggests that more neurofilament protein is expressed there relative to the perikaryon and primary dendrites. Five reddish cell bodies of B-type HCs (*) lie deeper in the INL. Uniformly thin greenish processes (arrows) are likely the axons of the B-type cell showing an upregulation of neurofilament protein in response to retinal detachment.
