Temperature induces variations in the retinal cell proliferation rate in a cyprinid.
We quantitatively evaluate the changes of the proliferative cell populations in the adult tench retinas maintained at 6 degrees C and 20 degrees C by both PCNA antigen detection and flow cytometry-based DNA measurements. Both the overall percentage of S-phase cells in the whole retinas and the number of PCNA-positive cells in each of the retinal layers were significantly lower in the tench kept at 6 degrees C, indicating that temperature affects the retinal germinal cell proliferation.
