It leads to multinucleated CMs if there is karyokinesis without cytokinesis during M-stage, and it leads to polyploid if there is DNA replication without karyokinesis and cytokinesis [31].
There was no distinct karyokinesis. On immunohistochemical staining, the pathology specimen of this tumor was positive for epithelial membrane antigen (Figure 3) but negative for glial fibrillary acidic protein.
Micronuclei are chromosomes or chromosomal fragments that fail to incorporate into either of the two daughter nuclei after karyokinesis. During formation of the reticulocyte in the bone marrow, micronuclei not extruded with the main nucleus are readily visualized and quantified, providing a simple, accurate assessment of chromosomal damage (Heddle 1973; Witt et al.
