Hitherto undescribed division activities in x-cells of dab Limanda lim
anda are presented. The observed features occurred in d very few sampl
es as clusters in certain regions of the conditions. The results suppo
rt the view that x-cells are dividing similarly to certain types of am
oebas. Additionally found cytoplasmic inclusions were Feulgen-positive
. Specific coated granules resemble retro-/lentiviruses, and are assoc
iated with the inclusion bodies.
