[Reutilization of labelled DNA precursors by the iris cells during the regeneration of the lens and retina in newts].
In the adult crested newts, the proliferating cells of the proximal and distal iris zones reutilize the labelled DNA precursors 4 days after triple injections of 3H-thymidine. The density of radioautographs (intensity of labelling per nucleus) under reutilization is 2.5--3 times weaker than under 3H-thymidine incorporation.
