... autoradiography reveals that histogenesis does persist until at least six months after metamorphosis. The rate of histogenesis is much decreased compared with that of larval stages but, like that of larval stages, it takes place at the ciliary margin. It is asymmetrically distributed in the retina, most...

...Hadar Emanuelsson ABSTRACT Females of the polychaete Ophryotrocha labronica have been pulse labelled with [5- 3 H] uridine, and the incorporation of label into the RNA of the oocyte-nurse cell complex was followed by light and electron microscope autoradiography. Up to its regression the polyploid...
