During reproduction, the macronucleus splits by a type of amitosis, and the micronuclei undergo mitosis.
Since neither of these depolyploidizations involves mitotic chromosomes, they conform to the broad definition of amitosis.
There are also multiple reports of amitosis occurring when nuclei bud out through the plasma membrane of a polyploid cell.
Similarly, two different kinds of amitosis have been described in monolayers of Ishikawa endometrial cells ( Fleming, 2014)
Division of the macronucleus occurs by amitosis, and the segregation of the chromosomes occurs by a process whose mechanism is unknown.
Rather than CNV's resulting from mitosis gone awry, some of this variation may arise from amitosis, and may be both desirable and necessary.
A couple of decades of research has shown that polyploid cells are frequently " reduced " to diploid cells by amitosis ( Zybina et al . ).
Furthermore, it is well to remember that ciliates possess a mechanism for adjusting copy numbers of individual genes during amitosis of the macronucleus . ( Prescott, 1994)
Amitosis by fissioning has also been reported in mammalian liver cells ( David and Uerlings, 1992 ) and human adrenal cells ( Magalhaes, Pignatelli, and Magalhaes, 1991 ).
Accordingly, and despite being very much out of fashion, a resurgence of interest in the role of amitosis in mammalian proliferation has been building over the past two to three decades.
