Hematoxylin-eosin staining (x100) revealed a large number of spindle cells rich in Vascellum, without distinct
karyokinesis (a).
Developmental consequences of
karyokinesis without cytokinesis during the first mitotic cell cycle of bovine parthenotes.
DISCUSSION: Nuclear aberrations are either acentric chromosome fragments or whole chromosome lagging in the normal
karyokinesis (12, 13).
Karyokinesis and cytokinesis in the maturation, fertilization and cleavage of Crepidula and other gastropoda.
These cells might have developed due to cytokinesis without
karyokinesis or due to the complete disintegration of the nuclear material.
The polyploidization of certain cells takes place during
karyokinesis. Some binucleated cells went through synchronized bimitosis, where simultaneous cellular divisions occurred in the two nuclei.
The nuclear membrane then dissolves, and a single brief mitotic-like
karyokinesis ensues.
