FIG. 6.

Synaptic interaction between the graft and the host tissue. Low magnification images demonstrate presence of SYP staining in the graft and in cat ONL adjacent to the graft. (a-a’) Shows co-labeling of cat retinal section immunostained with SYP and CALB2. (b-b’) High magnification images of the area marked with asterisks (*) and (**) in (a’), showing SYP-positive boutons in the graft and host ONL. Arrows indicate SYP-positive boutons in the graft. The inset in (b) is a high magnification of area marked with asterisk (***). Scale bar: 20 μm (b); 50 μm (b’). SYP, synaptophysin.
